Substitute Sherry for Wine in Sour dough cookies?
Sherry is wine, so yes, you can use Sherry in your recipe. Sherry is fortified, so its percentage of alcohol is perhaps a third more than most other wines. You don't say what kind of wine you usually use, but you could slightly dilute the Sherry with water to give it a close to equal percentage of alcohol as your usual choice. That would be the safest way to make the substitution.
