The submarine sandwich, the hoagie, the grinder – whatever you call it, that long roll piled high with meats, cheeses, and veggies is a culinary icon. But beyond the fillings, there’s a seemingly simple yet crucial ingredient that elevates a sub from ordinary to extraordinary: the oil. But what kind of oil is it, and why is it so important? The answer, as you might suspect, is a little more complex than you’d think.
The Importance of Oil in a Submarine Sandwich
Oil isn’t just a lubricant to prevent dryness; it’s a flavor carrier, a texture enhancer, and a key component in achieving that perfect sub sandwich experience. The right oil will meld the flavors together, adding its own subtle nuances while also preventing the bread from becoming soggy.
Without oil, a sub can feel dry, bland, and disjointed. The ingredients seem to sit separately, never truly combining into a harmonious whole. Oil provides the necessary moisture to bind the components, allowing the flavors to mingle and create a more satisfying bite.
Furthermore, the oil contributes to the overall mouthfeel. It creates a smooth, pleasant texture that complements the other ingredients. A good oil can even add a slight richness, making the sandwich feel more decadent and luxurious.
Decoding the Mystery: What Oils are Commonly Used?
There isn’t a single “official” sub oil. The choice of oil can vary greatly depending on the region, the specific sandwich shop, and the desired flavor profile. However, some oils are far more commonly used than others.
Olive Oil: The Classic Choice
Olive oil, particularly extra virgin olive oil (EVOO), is a frequent and arguably the most celebrated choice for subs. Its distinct flavor, ranging from fruity and peppery to grassy and robust, complements a wide range of sandwich fillings.
The quality of the olive oil matters significantly. A high-quality EVOO will impart a more complex and nuanced flavor, while a lower-grade olive oil may be more neutral and simply add moisture. Many sandwich shops boast about using “imported” olive oil, implying a higher quality and a more authentic flavor.
However, even within the realm of olive oil, there’s variety. Some prefer a milder olive oil to allow the other ingredients to shine, while others opt for a bolder variety to add a more assertive flavor.
Vegetable Oil: The Neutral Option
Vegetable oil, often a blend of different plant-based oils, is another common choice, particularly in larger chain restaurants. Its primary advantage is its neutral flavor and affordability.
Unlike olive oil, vegetable oil doesn’t contribute much in the way of taste. Its main purpose is to add moisture and prevent dryness. While it might not be as flavorful as olive oil, it’s a reliable and consistent option for maintaining a certain level of moisture in the sandwich.
However, the lack of flavor can be a drawback for those seeking a more complex and nuanced taste experience. Vegetable oil can also feel a bit heavier on the palate compared to lighter oils like olive oil.
Canola Oil: A Versatile Contender
Canola oil is another neutral-flavored oil that finds its way onto some subs. Similar to vegetable oil, it’s relatively inexpensive and widely available. It also has a high smoke point, making it suitable for use in situations where the oil might be heated.
While canola oil is a neutral option, it is not usually considered as desirable as olive oil due to its lack of flavor characteristics.
Infused Oils: Adding a Flavor Kick
For sandwich shops looking to add a unique twist, infused oils are a popular choice. These are oils that have been infused with herbs, spices, or other flavorings to create a more complex and interesting taste.
Garlic-infused oil is a particularly popular choice, adding a savory and pungent flavor to the sub. Chili-infused oil can add a touch of heat, while herb-infused oils can provide a more aromatic and herbaceous flavor.
The possibilities are endless when it comes to infused oils. They allow sandwich shops to create their own signature flavors and differentiate themselves from the competition.
Beyond the Oil: The Importance of Vinegar
While oil is a crucial component, it’s often paired with another equally important ingredient: vinegar. The combination of oil and vinegar is a classic pairing that adds both flavor and acidity to the sub.
Vinegar cuts through the richness of the oil and adds a tangy, refreshing counterpoint to the other ingredients. It also helps to balance the flavors and prevent the sub from feeling too heavy.
Red wine vinegar is a common choice, adding a fruity and slightly acidic flavor. White wine vinegar is a milder option, while balsamic vinegar can add a sweeter and more complex flavor.
The ratio of oil to vinegar is also important. Some prefer a higher ratio of oil to vinegar for a richer flavor, while others prefer a higher ratio of vinegar to oil for a tangier taste.
Regional Variations and Signature Styles
The type of oil used on subs can also vary depending on the region. Different regions have different culinary traditions and preferences, which are reflected in the types of oils they use.
In some areas, olive oil is the standard choice, while in others, vegetable oil or a blend of different oils is more common. Some regions might also have their own signature oils or infused oils that are unique to their area.
Individual sandwich shops also often develop their own signature styles when it comes to oil. Some might use a specific type of olive oil, while others might create their own custom blend of oils and vinegars.
The Sub Oil Landscape: A Look at Brands and Availability
While many independent sandwich shops make their own oil and vinegar mixture, some larger chains rely on commercially available products. These products often combine oil, vinegar, and spices for a pre-mixed, convenient option.
These pre-mixed dressings can offer consistency and ease of use, but may lack the nuanced flavor of a homemade blend. The specific brands used often remain proprietary information, as they contribute to the restaurant’s overall flavor profile.
The Art of Application: How the Oil is Applied
The way the oil is applied to the sub is just as important as the type of oil itself. Too much oil can make the sub soggy and greasy, while too little oil can leave it dry and bland.
Some sandwich makers drizzle the oil directly onto the bread, while others prefer to soak the fillings in oil before assembling the sandwich. The goal is to evenly distribute the oil throughout the sub, ensuring that every bite is perfectly flavored and moistened.
The amount of oil used is also a matter of personal preference. Some prefer a lightly oiled sub, while others prefer a more generously oiled sandwich.
Making the Perfect Sub at Home: Choosing Your Oil Wisely
Creating a delicious sub at home allows for complete control over the ingredients, including the oil. Experimenting with different oils and vinegars is key to finding your perfect combination.
Consider the other ingredients you’ll be using in your sub. If you’re using strong, flavorful meats and cheeses, you might want to opt for a milder oil to allow those flavors to shine. If you’re using blander ingredients, you might want to choose a more flavorful oil to add some depth.
Don’t be afraid to try different combinations of oils and vinegars. You might be surprised at what you discover.
Some popular homemade sub oil combinations include:
- Extra virgin olive oil and red wine vinegar
- Garlic-infused olive oil and balsamic vinegar
- Vegetable oil, white vinegar, and Italian herbs
Remember, the best oil for your sub is the one that you enjoy the most. Experiment, have fun, and find the perfect combination to create your ultimate submarine sandwich. The quest for the perfect sub is a personal journey, and the oil is a key ingredient on that path.
What type of oil is most commonly used on submarine sandwiches?
The most frequently used oil on submarine sandwiches, especially in traditional delis, is a blend of vegetable oils. This blend usually comprises soybean oil, corn oil, and/or canola oil. The choice of using a blend stems from its neutral flavor profile, allowing the other ingredients of the sub to shine through without being overpowered by the oil’s taste.
Furthermore, these vegetable oil blends are generally inexpensive and have a long shelf life, making them a practical choice for delis. The viscosity of the oil is also suitable for even distribution across the bread and ingredients, ensuring a consistent flavor and texture in every bite.
Why is oil used on submarine sandwiches at all?
Oil serves several crucial purposes in a submarine sandwich. Primarily, it acts as a flavor carrier, enhancing the taste of the other ingredients, such as meats, cheeses, and vegetables. The oil also helps to bind the ingredients together, preventing them from sliding around and creating a more cohesive eating experience.
Beyond flavor and cohesion, oil contributes significantly to the overall texture of the sub. It moistens the bread, preventing it from becoming dry and crumbly, and adds a pleasant richness and mouthfeel. This added moisture can also help to prevent the bread from becoming soggy when layered with wetter ingredients.
Can olive oil be used on submarine sandwiches? Is it a good choice?
Yes, olive oil can absolutely be used on submarine sandwiches, and in many cases, it’s a preferred option. Extra virgin olive oil, in particular, can impart a richer, more complex flavor to the sandwich. Its distinct taste adds a layer of sophistication and can complement certain ingredients, especially Mediterranean-inspired fillings. However, be mindful that it will be noticeable and may not suit every palate or sandwich combination.
While a flavorful choice, it is essential to consider the cost of olive oil compared to vegetable oil blends. For high-volume operations, the expense could be prohibitive. Additionally, the strong flavor of extra virgin olive oil may not be desired in all sub sandwiches, as it could overshadow the other ingredients if used excessively. A lighter, more subtle olive oil might be a better choice for general use.
Are there any healthier alternatives to the oils typically used on subs?
Yes, several healthier alternatives exist for those seeking to reduce their intake of saturated or processed fats. Avocado oil is a great option, boasting a mild flavor and a high smoke point, making it versatile for various applications. Its rich monounsaturated fat content offers health benefits, making it a more nutritious choice.
Another beneficial option is flaxseed oil, known for its high omega-3 fatty acid content. However, its flavor is quite distinct and might not be suitable for all submarine sandwiches. It’s best paired with specific flavor profiles that complement its earthy taste. Remember that flaxseed oil is also more perishable and requires refrigeration to prevent it from going rancid. Using smaller quantities of any oil, regardless of type, will also reduce the overall fat and calorie content of the sandwich.
Do different delis use different oils on their subs?
Absolutely. The type of oil used on submarine sandwiches can vary considerably from deli to deli. Some establishments stick with the traditional vegetable oil blends for their neutrality and affordability, while others may opt for more premium options like olive oil or specialty oils. The choice often reflects the deli’s overall philosophy regarding quality, cost, and target customer base.
Furthermore, some delis might even offer customers a choice of oils, similar to salad dressing options. This allows individuals to customize their sandwich according to their personal preferences and dietary needs. The oil selection can be a significant differentiator for a deli and contribute to its unique brand identity.
How does the type of oil affect the overall taste of a submarine sandwich?
The type of oil used profoundly influences the overall taste profile of a submarine sandwich. A neutral oil blend will allow the flavors of the meats, cheeses, vegetables, and condiments to take center stage without interference. The oil primarily serves as a lubricant and binder in this scenario.
In contrast, a flavorful oil, such as extra virgin olive oil or sesame oil, will contribute its own distinct notes to the sandwich. This can either enhance the existing flavors or create a completely new and interesting taste experience. The key is to select an oil that complements the other ingredients and enhances the overall enjoyment of the sandwich.
Is there such a thing as “sub oil” specifically designed for submarine sandwiches?
While there isn’t a universally recognized “sub oil” brand that is exclusively for submarine sandwiches, some manufacturers create oil blends specifically marketed towards deli applications. These blends are often designed to provide a balance of flavor, affordability, and suitability for various sandwich ingredients. They might contain herbs, spices, or other flavor enhancers to create a distinctive taste.
These “sub oil” blends typically focus on complementing common sandwich fillings without overpowering them. Some delis may also create their own proprietary oil blends by infusing oils with garlic, herbs, or chili peppers. These custom blends become a signature element of their sandwiches and a point of differentiation in a competitive market. Whether pre-made or custom, the goal is to elevate the sandwich beyond the sum of its individual ingredients.
