The best part about summer for any foodie is berry season, of course. Fresh strawberries, blueberries, raspberries, and blackberries overflow in farmers markets and grocery stores everywhere. In California, berry season is even more glorious because local farms allow you to pick your own berries in cute lil’ picnic baskets. You just can’t get them any fresher than that. And when you find yourself with a surplus of fresh fruit, why not turn it into homemade blueberry blackberry jam.

Spread this sweet jam on scones, toast, or make an extra big batch for a delicious pie filling—the options are endless.
