Frequently Asked Questions

How do I know if my canned relish is safe to eat?

Check for a sealed lid (it should not flex when pressed), clear liquid without cloudiness, and no mold or off smells. If any jar shows signs of spoilage, discard immediately. Never taste questionable relish.

Can I use different peppers for this recipe?

Yes! Poblano, jalapeño, or banana peppers work well. For safety, always use peppers with similar water content. Avoid watery peppers like bell peppers without roasting first. Never substitute with low-acid vegetables like tomatoes without adjusting the recipe.

Why is vinegar acidity so important for canning?

Vinegar must be 5% acidity or higher to prevent harmful bacteria growth. Never substitute with lower-acid vinegars like balsamic or wine vinegar unless specifically tested in the recipe. Always check labels for acidity percentage.
