With Memorial Day and the official start of summer mere weeks away, it’s the perfect time to infuse your own spirits. All you need are mason jars, some fruit, vegetables, or herbs, and your libation of choice. Mix it up, seal the jar, shake every so often, and in five days you’ll have the ultimate gourmet cocktail base, just in time for summer. Keep them for yourself to sip on all summer long, or wrap the jars with a bow and give them a hostess gifts.
