What is Tempeh and How is it Made?
Tempeh is a traditional Indonesian food made from fermented soybeans. It has a nutty flavor and a firm texture, making it a popular ingredient in various dishes. The fermentation process involves binding the soybeans together with a type of fungus called Rhizopus, which creates a compact cake. This process not only gives tempeh its unique taste but also increases its nutritional value by making the soybeans more easily digestible.
The fermentation process typically takes 24 to 48 hours, during which time the fungus breaks down some of the soybeans’ natural compounds, resulting in a higher content of vitamins, proteins, and fiber. This process also gives tempeh its characteristic appearance, with the soybeans bound together in a compact, cake-like form. Tempeh can be found in most health food stores and many supermarkets, often in the refrigerated or frozen section. It’s a versatile ingredient that can be used in a variety of dishes, from stir-fries and salads to sandwiches and soups.
Do You Need to Defrost Tempeh Before Cooking?
Defrosting tempeh before cooking is not always necessary, but it can be beneficial in some cases. If you’re using frozen tempeh, you can simply add it to your dish frozen, and it will thaw and cook quickly. However, defrosting it first can help the tempeh absorb more flavors and cook more evenly. To defrost tempeh, you can leave it in the refrigerator overnight or thaw it quickly by submerging it in cold water.
