Tempeh

What Is Tempeh?

Tempeh is a firm, sliceable food of Indonesian origin, obtained by inoculating boiled and partially dehulled soybeans with Rhizopus oligosporus starter and fermenting for 24-48 hours. The white mycelium network that binds the beans together gives tempeh its characteristic firm texture.

Unlike tofu, tempeh contains the whole bean (except the hull), so its texture is firmer and fibrous, and its taste more intense and mildly nutty. When cut, the bean pieces are clearly visible in its internal structure.

Nutritional Value of Tempeh

Tempeh is among the most protein-dense plant-based foods; 100 grams provides about 19 grams of protein. The fermentation process can reduce some nutrient-inhibiting compounds in soybeans, making mineral absorption easier.

What Are the Benefits of Tempeh?

With its high plant-based protein content, tempeh can be part of a balanced diet, especially as a meat alternative in vegetarian and vegan eating. There are studies showing that the fermentation process may increase digestibility.

This information is general; tempeh is a food, not a substitute for medical treatment. People with a soy allergy should not consume it.

How to Choose Tempeh?

Fresh tempeh should have a firm texture, covered with white-cream mycelium; black or blue spots and an ammonia smell are signs of spoilage.

• The surface should be evenly covered with white-cream mycelium, with no gray-black spots.
• The smell should be mildly mushroomy-nutty, with no sharp ammonia odor.
• The packaging should be vacuum-sealed and undamaged, and the expiration date should be checked.

How to Store Tempeh?

Unopened tempeh stays fresh in the refrigerator for about 1 week; for longer storage, it can be sliced and kept in the freezer for a few months. Once opened, it should be kept in an airtight container.

Using Tempeh in the Kitchen

Tempeh is sliced and fried, baked, or steamed; it is usually briefly boiled or steamed first to remove its raw, slightly bitter taste. It easily absorbs spices when marinated.

How to Cook Tempeh?

Thinly sliced tempeh is first boiled for about 10 minutes and drained, then marinated with soy sauce, garlic, and ginger and pan-fried until golden brown. This method both reduces the mild bitterness and increases spice absorption.

How to Make Fried Tempeh?

Marinated tempeh slices are fried in a little oil or a deep fryer until the edges are crispy; they are added as a meat alternative to sandwich, salad, or rice bowl recipes.

Which Recipes Use Tempeh?

Tempeh is used in place of meat in tempeh sauté, tempeh sandwich, tempeh skewers, and buddha bowls. When marinated and grilled, it also offers a meat-like texture and flavor.

Are the black spots on tempeh harmful?

A few small black/gray spots are generally caused by sporulation and are harmless; however, if there is widespread discoloration, softening, or an ammonia smell, the tempeh should be discarded.
