Is it possible to make this without the cornstarch and soy sauce? Was craving sweet and sour chicken but I didn't have any soy sauce or cornstarch.

well, you dont need soy sauce for sweet and sour chicken, but you do need a means of thickening the sauce. unless you just want to eat it unthickened. if youre desperate enough you could just do that. what other thickeners do you have? got flour? you could do it with that, although itll be a lil different.

nvr heard of soy sauce in SS sauce b4
potatostarch works as well

yeah u need starch... it can be cornstarch, potato starch, topioca starch... i wouldnt recommend flour though.

how come if I may ask, should work fine, just double up on the flour (two tsp of flour = one tsp of cornstarch) Is it as good? Nah, but it does thicken it up without changing the flavor much, only thing you would have to worry about is it won't hold up in the fridge good. Will deteriorate pretty fast.

The sauce would be lumpy if you used just flour and if you made a roux it would taste different. You could use a flour slurry i suppose but I've never been fond of them, I can always taste the flour.

technically u can use flour, and make it without lumps, and cook it enough so you dont taste the flour.... but the texture will not be right...

most people dont have potato starch on hand anyway, but even if he did, it wouldnt be quite the same with that, either.

yah topioca or corn starch will give the best result

as long as you stir it up nice and it's at a simmer should be able to do it fine without having lumps, not saying it's the best by any means, but if you are out and can't get to the store than it works in a pinch.
