Sweet & Sour questions
Can I use fresh pineapple?
Blitz fresh pineapple with a splash of water or pineapple juice to replace the tin and its juice. It gives a fresher, slightly sharper sauce.
What vegetables and tofu suit it?
Crispy tofu, peppers, onion, carrot and mangetout all work well. Stir-fry them first, then add the cubes and toss until glossy.
How do I make it thinner for dipping?
Thaw a cube and stir in a little water or rice vinegar until it's the consistency you want.
