Oyster Sauce Substitute?
oyster sauce is thick and almost gelatinous. it is a great thickener and is very salty. i recommmend using a cornstrach/water mix and adding soy sauce. will not taste the same but will give you the thickening, dark colour and saltiness. i have also seen vegan oyster sauces available but as earlier stated, they are not certified.
It depends how strictly kosher you are; I have bought "vegetarian oyster sauce" made from oyster mushrooms - no seafood, but not certified kosher.
. Perhaps some exists certified kosher. I googled "kosher oyster sauce" (yes, I know that is like kosher ham, but there are quite a few hits on substitutes). http://www.kosherblog.net/2005/02/14/...
Perhaps you can substitute another Asian sauce? What recipe do you want to make?
Yes, strictly kosher, Orthodox hashgacha required, etc.
Most of what I find on line is out of date; I have had no success finding anyone who carries any kosher oyster-flavor sauce.
I just want it in my larder for any recipe that asks for it - it pops up a lot in Weight Watchers recipes.
I looked at the Soy Vay line - they are all kosher and parve, but I don't see (vegetarian) oyster sauce. Often it is a matter of producers of products that have nothing inherently non-kosher about them (vegetarian oyster sauce, soya-based vegetarian "cream") to see certification as worth their while.
