Preserving produce is a year-round pursuit for many, but it definitely goes into high gear in summer. These are some of the best Crock-Pot jelly, jam, preserve, and condiment recipes to fight food waste, stock your pantry, and give as gifts any time you’re feeling generous.

The Crock-Pot just might be the perfect appliance for making ketchup, jam, fruit butter, and other cooked-down things. These are all things best left to transform on their own, in the presence of steady, pervasive heat. The other great thing about slow cooking in summer is you can set it, and flee the stuffiness of the kitchen.

Many of these recipes star peak summer produce, of course, but there are others you can make any time you get the urge…bacon knows no season, after all.

If you want to make these last a lot longer, can them—see our beginner’s guide to canning, essential canning supplies, and more handy canning tips if you’re not sure where to start. But if you skip the canning process, you can still keep most of these in the fridge for at least a few weeks. Some can be stashed for a few months in the freezer.

We don’t think you’ll have any problem getting through them quickly, though, because they’re all delicious.
