Press the tofu by slicing it & sandwiching it between teatowels. Put something heavy on it & leave for half an hour-overnight.
In a sealable container, mix together the Blackbean Sauce, Soya Sauce & Black Vinegar
Dice the tofu and add to the container with the marinade. Give it a shake to distribut the marinade evenly
Leave to marinade for at least half an hour. The longer you leave it, the tastier it will be!
To cook the tofu, heat the oil in a wok. You want it hot so it sizzles
Open up your container and add the cornstarch. Close the lid and shake it so that the cornstarch evenly coats the tofu
Add a single piece of the tofu to the wok. If it sizzles, it's ready to cook with.
Add the rest of the tofu in batches, removing them once crispy to a clean paper towel to drain.
Don't throw away the rest of the marinade! You need it for the noodles!
