Soft Braised Tofu (Cantonese Style) | IDDSI Level 5 Recipe

IDDSI Level 5 (Minced and Moist) | 30 minutes | Easy | Vegetarian

Red-braised tofu (紅燒豆腐) is a beloved Cantonese home dish that adapts naturally to IDDSI Level 5 when prepared with silken or soft tofu and a well-flavoured braising sauce. The tofu absorbs the umami-rich soy and ginger sauce while retaining its soft, moist structure — yielding individual pieces that break apart easily under minimal pressure from a fork or tongue, without requiring a knife. This is an accessible, protein-rich dish that residents familiar with Cantonese cooking will recognise and accept readily.

Ingredients (2–3 servings)

• 400 g silken or soft firm tofu (not extra-firm; must yield easily to fork pressure)
• 3 dried shiitake mushrooms (rehydrated, stems removed, finely diced — pieces under 4 mm)
• 2 cloves garlic (minced)
• 2 slices fresh ginger (minced)
• 2 tablespoons light soy sauce
• 1 tablespoon dark soy sauce
• 1 tablespoon Shaoxing rice wine (optional; omit if alcohol-free is required)
• 1 teaspoon sugar
• 150 ml vegetable stock
• 1 tablespoon cornstarch dissolved in 2 tablespoons cold water
• 1 tablespoon vegetable oil
• 1 teaspoon sesame oil (for finishing)
• Finely sliced spring onion for garnish (optional; remove if residue risk)

Method

1. Drain tofu and pat dry with paper towels; cut into 2 cm cubes — handle gently to avoid crumbling
2. Heat vegetable oil in a non-stick wok or frying pan over medium heat; add garlic and ginger and sauté for 30 seconds until fragrant — do not brown
3. Add diced rehydrated mushrooms; stir-fry for 2 minutes
4. Add soy sauce, dark soy sauce, Shaoxing wine, sugar and vegetable stock; bring to a simmer
5. Gently lower tofu cubes into the braising liquid; spoon the sauce over the top; do not stir aggressively
6. Cover and braise on low heat for 8 minutes, basting twice; the tofu will absorb colour and flavour
7. Stir the cornstarch slurry and pour it around the edges of the pan; gently tilt the pan to mix; cook for 1 minute until the sauce thickens into a glossy coating
8. Remove from heat; drizzle with sesame oil; portion carefully to maintain cube shape

Texture Test

IDDSI Level 5 (Minced and Moist) confirmation: Each tofu cube should break apart easily when pressed with the flat of a fork using light pressure — it should not require cutting with a knife. The braised pieces must be moist throughout. Fork test: pieces should be no larger than 4 mm after being pressed flat.

Safety Notes

⚠️ Do not use extra-firm tofu — it may not break down adequately under fork or tongue pressure and could pose a choking risk.

⚠️ Confirm mushroom dice size — mushroom pieces must be 4 mm or smaller after cooking; larger pieces can be difficult to manage at Level 5.

⚠️ Check tofu integrity — different batches of silken tofu vary in firmness; always apply the fork pressure test before serving.
