If you've made too much homemade salsa, you might try preserving them so you can use them again in the future.
How to Freeze Salsa
You can freeze your salsas by pouring them into a freezer safe container. Freeze them up to 6 months and thaw for later use. You'll likely loose any crunchy texture of chunkier salsas, but the thawed salsas work great for incorporating into sauces, soups, or slow cooker recipes.
How to Can Salsa
You can preserve your salsa by canning if you have a good canner. Here is a great resource for canning salsas at the National Center for Home Food Preservation.
