Dim Sum Salt and Pepper Tofu 椒盐豆腐 — Yung Kitchen
Tofu is the hardest dish. Not because of the technique – because of the expectation. Most people have eaten it soggy, soft, without character. When it comes out of the oil crisp, they see it for the first time. That is the moment the dish begins.
– Li Xiejie, Head Chef
What is Salt and Pepper Tofu?
椒盐豆腐 (jiao yan dou fu) – salt and pepper tofu – is a Cantonese dim sum dish. Tofu fried until a crisp crust forms, then seasoned with salt and Sichuan pepper (椒盐, jiao yan). 150 g, vegan, EUR 10. The dish lives from the contrast between the crisp exterior and the soft interior.
椒盐 (jiao yan) is a spice blend of toasted Sichuan pepper and salt – a Cantonese classic. Here: exclusively on tofu. Fully plant-based.
The Maillard reaction – Chef Li Xiejie’s tofu philosophy
The difference between soggy and good tofu is a technical question. Tofu contains a lot of water. When placed directly in the pan, the water evaporates and it steams rather than frying. Result: no crust, soft surface, neutral flavour.
Chef Li Xiejie fries the tofu. At sufficiently high temperature, the Maillard reaction occurs on the tofu’s surface – the same reaction that browns bread and makes steaks aromatic. Amino acids and sugars react together and create hundreds of new aroma compounds. This is not fat – this is chemistry.
The frying takes only a short time. But it fundamentally changes the character of the tofu. Then 椒盐 – Sichuan pepper and salt – goes onto the hot surface. The spices adhere and penetrate the crust.
Each ingredient and its TCM connection
Tofu (豆腐) – cooling, nourishes Yin, plant protein
Tofu is cooling and mildly sweet in TCM. It nourishes Yin, moistens dryness and cools heat in the body. It strengthens the spleen and provides plant protein, calcium and isoflavones. Isoflavones are phytoestrogens – plant compounds structurally similar to oestrogen that can support hormonal balance.
椒盐 – Salt-pepper crust (Sichuan pepper + salt)
Sichuan pepper (花椒) is warming – the direct counterweight to the cooling nature of tofu. In TCM it warms the centre, promotes qi flow and activates the digestive system. Tofu cools, Sichuan pepper warms. Salt in TCM belongs to the Water element and has a descending and digestion-supporting action.
TCM principle: tofu (cooling/Yin) + Sichuan pepper (warming/Yang) = deliberate balance. The dish is balanced within itself.
How it is prepared
- Drain the tofu. Place firm tofu between kitchen towels and press out water – at least 15 minutes. This step determines crust quality.
- Cut into pieces. Even cubes or strips – approx. 2-3 cm. Even size ensures even cooking.
- Fry. Fry in hot oil (160-170 C) until the surface is golden and crisp. The Maillard reaction needs temperature – oil that is too cool produces no crust.
- Drain. Rest on kitchen paper – remove excess oil.
- Apply 椒盐. Toasted Sichuan pepper and salt directly onto the hot tofu – immediately after frying, so the spices adhere to the hot surface.
A note on health
Tofu is one of the most nutrient-dense plant protein sources: complete amino acid profile, calcium, iron, magnesium. The isoflavones (genistein, daidzein) from soy are intensively researched in nutritional science – their effect on hormonal balance is studied both for women in menopause and in cancer prevention research.
Frying adds oil – relevant for caloric content. The portion (150 g) as a dim sum dish is part of a varied meal, not a standalone main course.

Frequently asked questions
Is this dish completely vegan?
Yes. Salt and Pepper Tofu contains only tofu, Sichuan pepper, salt and oil – no animal products. It is one of the few dishes that is fully vegan and simultaneously provides protein in a meaningful quantity.
Why fried tofu rather than pan-cooked?
Because the Maillard reaction creates aromas that pan-cooking cannot achieve – the temperature is not high enough to brown the surface fast enough. Frying gives tofu an even, crisp crust on all sides in a short time. That is the honest answer.
What is 椒盐 (jiao yan)?
椒盐 is a Cantonese spice blend: toasted Sichuan pepper and salt, often with white pepper. The Sichuan pepper creates the characteristic numbing sensation (麻), the salt binds everything. Here it goes on tofu – no other proteins, no seafood. The dish is explicitly vegan.

What science says about tofu and soy isoflavones
Soy isoflavones: phytoestrogens and hormonal balance
Tofu contains genistein and daidzein – isoflavones from soy structurally similar to human oestrogen. A meta-analysis in Nutrients (2022) shows that soy isoflavones significantly reduce menopausal symptoms in postmenopausal women and can improve cardiovascular markers.
Plant protein: complete amino acid profile
Unlike many plant proteins, soy contains all nine essential amino acids. Tofu provides approx. 8g protein per 100g – similar to lean meat – without cholesterol. As a dim sum portion (150g), this delivers approximately 12g protein: meaningful for a plant-based diet.
