Any other liqueur (e.g. vermouth, white wine, even a wine cooler) or juice (e.g. lemonade), Ginger Ale, or even water could be used instead (if you're dealing with a recipe). You could also omit the sherry--it all depends on what you think the result will taste best like.
sherry
No, because sherry is red and it tastes different, so unless you want your food to change color and taste, don't substitute sherry for white wine.
Yes, but make sure it is dry.
Red wine vinegar, if you have it.
Sometimes.
Dry vermouth, but use a little less.
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.
Yes, any good quality white wine can be used instead of sherry.
It will change the taste.
Ian hines is the best recipe
You can use equal parts dry sherry/pale sherry wine; not the cooking wine... the drinking wine. :)
You can but it is stronger in flavour so don't use as much.
