Wine provides acid to food in order to fight bland or flat flavor. Just think of lemon which is another type of fruit acid. When lemon is used on vegetable salads it provides flavor and a lift or brightness to the taste.
Wines are used partially for the touch of flavor that they add and for the fact that the alcohol will disolve certain flavors and pull them out of herbs and other ingredients. White wine doesn't change the color of the sauce or dish, while red wines are used with darker foods like meats, stews and tomato sauces.
Good flavoring
yes of course
Dry white wine is normally used for savory dishes. Sweet white wine is rarely used in cooking.
Yes
Yes but you will change the outcome and not always in a good way.
No, White vinegar is plain Acetic acid in water, but either as a simple chemical mix (usually very cheap or cleaning grade vinegar) or through fermentation of distilled alcohol (akin to Vodka). White wine vinegar is made from the fermentation of real White wine. As such White vinegar has a simple acidic taste, whilst White Wine vinegar retains much of its original White wine taste, with its alcohol replaced by the Acetic acid of vinegar.
yes you can _______ Red cooking wine would be a better substitute as sherry has a red wine base. White cooking wine wouldn't have the same depth.
No. Cooking wine does not contain vinegar, and would introduce too much salt.
Yes but you will change the outcome
You can use equal parts dry sherry/pale sherry wine; not the cooking wine... the drinking wine. :)
White cooking wine is supposed to taste like a dry white wine, while a sauterne cooking wine will be much sweeter. Sauterne wines are dessert wines, so are very sweet; but add nice flavor to sauces for meats such as pork or chicken. I prefer to use real wine, not "cooking wine", and the commercial made cooking wines are full of preservatives and are usually sweeter than the real thing. Just remember to use a good wine, one you would drink, because when you cook with it, it will reduce and concentrate in flavor. If you start with a bad tasting wine, you'll just end up with a concentrated bad tasting wine.
yes you could usually a red wine or white but red one is most often used for cooking because vibrant flavour
No, you can not because there will be differents types of plavor. The white whine is actual whine, whereas the white cooking whine is for cooking, and so you cannot subsitute that with white whine. you could look up subsitues on google, im sure there are many subsitutes other that white wine.
