Sauce-Braised Crab

Ingredients

• 500 g crab (river crab preferred, or swimming crab)
• 30–50 g bean paste
• 0–15 g rock sugar
• 15 ml dark soy sauce
• 20 ml unrefined rapeseed oil
• 15 ml tomato paste
• 5 ml rice wine
• 10 g ginger
• 10 g spring onion
• 1 egg
• 50 g pork mince
• 500 ml water

Method

Split the crabs lengthways through the head and down the midline of the tail. This halving exposes the meat to direct contact with the braising sauce and steam, accelerating cooking and flavour absorption compared to whole crabs.

Heat the rapeseed oil in a wok over a medium-high flame until it shimmers. Add the minced ginger and bean paste together — the bean paste's fermented-condiments salt and umami-rich compounds need heat to bloom and disperse through the oil. Stir constantly for 60–90 seconds; you'll smell the raw edge leave the aromatics. The ginger should begin to colour at the edges. Add the tomato paste and rice wine in quick succession, stirring to prevent scorching. The tomato paste deepens the umami base (glutamates multiplying the bean paste's effect) whilst the rice wine's alcohol burns off, leaving behind subtle sweetness and complexity. Sprinkle in the rock sugar and let it dissolve fully — watch for the surface to turn syrupy and glossy, not crystalline. This takes 2–3 minutes. Stir in the dark soy sauce and taste the sauce; it should be salty, funky, slightly sweet, with ginger's heat threading through.

Spread a thin layer of this sauce paste across the base of a heatproof dish. Arrange the crab halves cut-side down in the sauce — the exposed flesh will absorb the braising liquid. Scatter ginger slices and spring onion segments over the shells. If using the egg, crack it directly over the crabs so the white and yolk distribute as they steam and set. If using pork mince, crumble it evenly across the crab meat as a second protein and flavour layer. Pour the remaining sauce around (not over) the crabs, then add the 500 ml water — this becomes your steaming liquid and basting medium.

Cover the dish tightly with foil or a lid. Steam for 12–14 minutes at a hard boil; the meat will turn opaque throughout and pull slightly from the shell. Test by prodding the thickest part of the leg — it should give no resistance. The sauce will have emulsified slightly with the crab's natural juices, thickening to a glaze.

Finish with a scattering of fresh chopped spring onion and serve directly from the dish, spooning sauce over each portion. The heat carries the finished flavours to the table.
