I love cooking with wine… and sometimes I add some to my cooking too. Cooking with alcohol, especially wine, can release elements in food that would otherwise not come out, specifically tomatoes and meats.
If you have a little bit of wine left over in a bottle but cannot finish it, instead of letting it spoil on your counter, you can pour it into an ice cube tray and freeze it.
This way you are not wasting that last drop and you are keeping the wine fresh for future cooking. Or have a hand at making some ancient wine? Try making mead.
