Mixed Mushroom Soft Stir-Fry | IDDSI Level 5 Recipe

IDDSI Level 5 (Minced and Moist) | 25 minutes | Easy | Vegetarian

Using a combination of three mushroom varieties creates a layered umami profile while providing slight variations in texture that make the dish more interesting to eat. Thorough cooking followed by gentle braising ensures all pieces are soft enough to be mashed with tongue pressure alone. All pieces are cut to no larger than 1.5cm to comply with IDDSI Level 5 (Minced and Moist) size requirements.

Ingredients (2–3 servings)

• 4–5 fresh shiitake mushrooms (stems removed, caps sliced thinly)
• 100g oyster mushrooms / sechin mushrooms (torn into thin strips by hand)
• 80g enoki mushrooms (root ends removed, halved in length)
• 3 slices fresh ginger (cut into fine shreds)
• 2 cloves garlic (minced)
• 1.5 tablespoons vegetarian oyster sauce (素蠔油)
• 1 teaspoon soy sauce
• 1 teaspoon sesame oil
• 1 tablespoon cornflour slurry (1 teaspoon cornflour mixed with 2 teaspoons water)
• 1.5 tablespoons vegetable oil
• 3 tablespoons water

Method

1. Prepare all mushrooms: slice shiitake caps to no more than 5mm thickness; tear oyster mushrooms into strips; halve enoki mushrooms in length — all pieces must not exceed 1.5cm in any dimension after cooking
2. Heat wok over high heat; add oil; stir-fry ginger shreds and garlic for 30 seconds until fragrant
3. Add shiitake slices; stir-fry over medium-high heat for 2 minutes until softened and releasing moisture
4. Add oyster mushrooms and enoki; add 3 tablespoons water; toss to combine and stir-fry for 2 minutes
5. Reduce to low heat; add vegetarian oyster sauce and soy sauce; toss until evenly coated
6. Cover and braise on low heat for 3–4 minutes until all mushrooms are completely tender throughout
7. Fork-pressure test: mushroom pieces should deform immediately with gentle fork pressure, offering no resistance; if not yet soft enough, continue braising for 2 more minutes
8. Add cornflour slurry; increase to high heat and toss briefly until the sauce thickens and coats all mushroom surfaces evenly
9. Finish with sesame oil; toss once more; confirm all pieces are no larger than 1.5cm before plating

Texture Test

IDDSI Level 5 (Minced and Moist) confirmation: Press a mushroom piece with a fork using light pressure — it should immediately deform and flatten with no resistance. All pieces must measure no more than 1.5cm. The accompanying sauce should be fluid enough to coat the mushrooms (not gel-like or sticky). The dish should not form lumps or clump together.

Safety Notes

⚠️ Remove enoki root ends completely — the base cluster of enoki mushrooms is significantly tougher than the upper stems; cut at least 2cm above the root end to ensure all included portions are adequately soft after cooking.

⚠️ Confirm piece size before serving — use a visual check against a 1.5cm reference (approximately the width of a fingertip) for all pieces; any oversized pieces should be cut down before plating.

⚠️ Sauce consistency — if additional liquid thickening is required for the resident’s IDDSI drink level, apply separately — do not over-thicken the mushroom sauce itself, as this may cause it to become sticky and difficult to manage in the mouth.

Sourcing in Hong Kong

• Fresh shiitake: Wet market vegetable stalls; choose firm caps with no sliminess
• Oyster mushrooms (秀珍菇): Supermarkets or wet markets, also sold as flat mushroom or pleurotus; softer texture than shiitake, cooks quickly
• Enoki mushrooms (金針菇): Supermarket chilled vegetable section; choose bundles with clean, even stems and no sliminess

Enoki mushrooms specifically contain flammulin, with research suggesting immune-stimulating properties.
