Buddhist vegetarian cooking in China — *su cai* — has a documented history extending over 1,500 years, primarily associated with monastery kitchens. The principle of braising tofu with mushrooms (particularly dried shiitake, whose soaking liquid is one of the most concentrated natural umami sources in Chinese cooking) appears in vegetarian texts from the Tang dynasty. Today it represents both the apex of Chinese Buddhist cooking and a standard of the everyday household table.
Braised tofu with mushrooms is the foundational technique of Chinese vegetarian cooking — a preparation that uses the tofu-frying stage, the mushroom soaking liquid, and a carefully calibrated braise to transform humble ingredients into something meaty, deeply savoury, and texturally complex. The technique is taught to demonstrate that Chinese cuisine produces compelling vegetarian food not by imitation of meat but by developing the intrinsic flavour potential of its own ingredients.
Braised tofu fits equally in a simple weekday rice meal and a more elaborate vegetarian banquet. Its deep, meaty character means it functions as the protein centrepiece — a role it performs without any need for meat. Alongside plain steamed rice, a plate of garlic-tossed green vegetables, and pickled vegetables (FD-41), it constitutes a complete and deeply satisfying meal. The richness of the braise needs the simplicity and neutrality of rice to ground it.
- **Tofu selection:** Firm tofu (laodoufu or extra-firm) is required — silken tofu will disintegrate in the braise. Press the tofu for 20–30 minutes before cooking to remove excess moisture. - **Pan-frying the tofu:** Cut into slices or triangles, season with salt, and pan-fry in a small amount of oil until golden on both sides. This creates a slightly firm, flavour-absorbing exterior and ensures the tofu holds its shape through the braise. Do not skip this stage — soft, unfried tofu has no textural interest in a braise. - **Dried shiitake mushrooms:** Soak in cold water for a minimum of 2 hours (or hot water for 30 minutes). Squeeze out the liquid and reserve — this soaking liquid is the backbone of the braise. Strain it through a fine cloth to remove any grit; it is too valuable to discard. - **The braise liquid:** Mushroom soaking liquid, a small amount of soy sauce, oyster sauce (or mushroom-based vegan oyster sauce), a small amount of dark soy sauce for colour, Shaoxing wine, a pinch of sugar, and white pepper. The liquid should not cover the tofu — this is a shallow braise, not a stew. - **Braise duration:** 15–20 minutes over medium heat, turning the tofu gently once. The liquid should reduce to a thick, glossy glaze that coats the tofu and mushrooms. - **The cornstarch finish:** A small amount of cornstarch dissolved in cold water, added in the final 2 minutes, thickens the remaining liquid into a velvety glaze. Do not use too much — the result should be saucy and glossy, not gluey. - **Aromatics:** Garlic, ginger, and fresh spring onion in the base; a small amount of sesame oil at the very end. Decisive moment: The final reduction — when the liquid has reduced to approximately a third of its original volume and begins to coat the tofu in a thick glaze. Add the cornstarch slurry here, toss once, and remove from heat immediately. If overcooked past this point, the glaze becomes tacky and the tofu begins to break down. Sensory tests: - **Sight:** Deep mahogany colour from the dark soy and mushroom liquid. The tofu should retain its shape — no crumbling. The sauce should be glossy and coat the tofu surfaces visibly. - **Smell:** The intensely concentrated umami of reduced mushroom soaking liquid — earthy, deep, slightly sweet. Soy sauce and sesame oil rounding the background. - **Feel:** The tofu should offer gentle resistance — the exterior slightly firmed by pan-frying, the interior tender but holding. The mushrooms should be fully tender and yielding. - **Taste:** Deep, layered umami — this is the dish where the complexity of properly reduced mushroom liquid becomes apparent. Soy sauce depth, slight sweetness balancing the earthiness, the clean aromatic finish of sesame oil.
- The mushroom soaking liquid from dried shiitake is one of the most powerful umami liquids available in Chinese cooking — treat it as a reduced stock and use it wherever depth is needed. - Fresh shiitake can be substituted but will produce a noticeably less complex braise liquid. Use both fresh and dried for the best result — dried for the liquid, fresh for the texture. - Adding glass noodles (bean thread vermicelli, soaked for 10 minutes) in the final 5 minutes of the braise creates a more substantial, filling dish. - A fried egg (sunny side up, crispy edges) served alongside plain rice and this tofu braise is the classic Shanghainese comfort meal.
- Tofu breaking apart in the braise → not firmly pressed or pan-fried before braising; or braise stirred too aggressively - Thin, watery sauce → insufficient reduction; or mushroom soaking liquid was diluted (mushrooms not soaked long enough to give a rich liquid) - Muddy, one-dimensional flavour → soaking liquid not used; using plain water instead eliminates the umami backbone - Dish tastes too salty → dark soy sauce and oyster sauce both high in sodium; reduce both quantities slightly and adjust at the end
