sweet and sour sauce

yesterday, i my post was about making wontons...and there were no specific quantities given, but now i give specific quantities for sweet and sour sauce. i know people who eyeball this, but i like my sweet and sour sauce consistent.
i love deep fried wontons with this. i really do.....

1/3 cup vinegar (i use apple cider vinegar)
1 cup water
3/4 cup sugar
pinch of salt
pinch of pepper
3 tablespoons tomato sauce

2 tablespoons cornflour/1 tablespoon wheaten cornflour
2 tablespoons water

place the vinegar, water, sugar, salt and pepper and tomato sauce in a medium saucepan and bring to the boil.
meanwhile, dissolve the cornflour in the water and pour into the boiling vinegar, whisking the whole time. once the sauce has come to the boil, it is ready to serve with the deep fried wontons....or whatever you like.

if you want the sweet and sour sauce they have with pork, just add some stir fried capsicum, onion, carrots and pineapple to the sauce. if you decide to do this, don't waste the syrup from the pineapple (if you're using canned pineapple) and use it to replace the water whilst making the sauce.
