Prawns is one of my favourite proteins to cook with because its delicious, really good for you and you can buy a big bag and freeze them. So this recipe is just for one person, so using a protein like prawns is very easy to portion just for yourself or scale it up to feed a family.

What is black bean sauce?

Black bean sauce gets its character from preserved black beans which are salted and fermented soybeans that are intensely savoury, slightly funky, and soft enough to partially dissolve into the sauce as it cooks.

In this stir-fry they go in with ginger, garlic, and spring onion in a hot wok, then a cornflour-thickened sauce mixture goes in and tightens everything around the prawns in under a minute. It’s a 5-minute cook once everything is prepped.

The beans need a short soak before cooking, 30 minutes to an hour, to draw out excess salt and soften them. Keep a tablespoon of the soaking liquid as it carries fermented flavour and goes back into the sauce. The other thing that makes or breaks this dish is wok heat. The capsicum, ginger, and garlic need to hit a very hot surface fast. A warm pan steams everything and you lose the seared, slightly charred edge that a proper stir-fry should have.

Ingredient Notes

Preserved black beans: Salted and fermented soybeans, sold in bags or jars at Asian grocery stores. They’re intensely savoury and the base flavour of the entire dish. Always soak them before using as they can be very salty straight from the packet. Don’t discard the soaking liquid: a tablespoon of it goes back into the sauce.

Shaoxing wine: A fermented Chinese rice wine that adds depth and a subtle savoury sweetness when it hits the hot wok. It deglazes the pan and lifts the caramelised bits from the capsicum. Dry sherry is the closest substitute. Mirin also works but it’s sweeter, so use a little less.

Peanut oil: Has a high smoke point, which makes it well suited to wok cooking where the oil needs to handle very high heat without burning. Vegetable or sunflower oil are fine substitutes if you don’t have peanut oil on hand.
