Tempeh — the fermented soybean cake from Indonesia — is having its moment in India, and for good reason: it packs around 19g of protein per 100g, more than paneer, with probiotics and fibre that mock meats don't have. Buying it ready-made is still hard outside metro cities, but making it at home is genuinely doable with a starter culture, soybeans and a warm corner of your kitchen — which in most of India is easy to find.
What is tempeh?
Tempeh is whole soybeans fermented with the Rhizopus mould, which binds the beans into a firm, sliceable cake. Unlike tofu (which is made from soy milk), tempeh keeps the whole bean — so it keeps the fibre, more of the protein, and gains B vitamins and easier digestibility from fermentation. The flavour is nutty and mushroom-like, and it absorbs Indian marinades beautifully.
What you need
- Whole soybeans — available at any Indian grocery; 500g of dry beans makes roughly 1kg of tempeh.
- Tempeh starter culture (Rhizopus spores) — a few grams per batch.
- Vinegar — acidifies the beans so the right mould wins.
- Perforated bags or banana leaves — the mould needs a little airflow.
- A warm spot (28–32°C) — room temperature across most of India for most of the year; no incubator needed except in winter in the north.
Step-by-step method
- Soak the soybeans overnight (8–12 hours).
- Dehull: rub the soaked beans between your hands to split them and float off the skins — the mould binds much better on split beans.
- Cook the beans until tender but not mushy — about 30–40 minutes of boiling, or 2–3 whistles in a pressure cooker with care.
- Dry and acidify: drain thoroughly, towel-dry the beans (wet beans grow the wrong microbes), stir in 2 tablespoons of vinegar per 500g.
- Inoculate: cool to body temperature, sprinkle in the starter, mix very well.
- Pack into perforated bags or banana leaves about 3cm thick.
- Ferment 24–48 hours at 28–32°C. By hour 24 you should see white mycelium knitting the beans together; the cake is done when it is firm, white and holds together when sliced. A faint mushroomy-nutty smell is right; black spore patches near air holes are normal and harmless.
How to steam tempeh (and why you should)
One of the most-searched tempeh questions, and the answer matters: steam fresh tempeh for 10 minutes before marinating or frying. Steaming mellows any bitterness, opens the cake so marinades soak in, and pasteurises home-made batches. After steaming: marinate like paneer, then pan-fry, air-fry, grill, or crumble into keema and bhurji.
Troubleshooting
- No white growth after 24h — too cold, or the starter was dead. Move somewhere warmer.
- Slimy or ammonia smell — bacterial contamination; discard and towel-dry more thoroughly next time.
- Grey/black patches — normal sporulation near air holes; fine to eat.
- Beans not binding — packed too loose or too thick; aim for a 2–3cm layer, firmly pressed.
Tempeh in an Indian high-protein diet
Per 100g, tempeh brings roughly 19g protein — ahead of paneer (≈18g, with far more saturated fat), tofu (≈8g) and cooked dal (≈9g) — plus fermentation benefits none of them offer. For vegans and vegetarians chasing protein targets, a weekly tempeh batch is one of the cheapest per-gram protein sources available in India.
Frequently asked questions
Is tempeh available in India?
Ready-made tempeh is available in some metro cities, but supply is patchy — which is why home fermentation with a starter culture is the reliable route across India.
Is tempeh healthier than paneer?
Tempeh has similar protein to paneer with a fraction of the saturated fat, plus fibre and fermentation benefits. Paneer wins on convenience; tempeh wins on nutrition per rupee.
Can I make tempeh with other beans?
Yes — chickpeas, peanuts and even mixed dals ferment well with the same starter and method, though soybeans give the classic texture and the highest protein.
How long does homemade tempeh last?
3–5 days refrigerated, or 2–3 months frozen. Steam before freezing for best texture.
