Featured Question

We have already made 14 pints of red salsa & are now looking at using our green tomatoes in salsa verde. I was reading a recipe on line which said you cannot use fresh lemon or lime juice for canning. That's all we used in our red version. (1/2 cup per 7 pints) I'd hate to think we'd have to throw this out! If there's a risk, can I open them, recook it and freeze it?
