Step one: Juice a bunch of lemons (I got 1 1/2 cups from 8 meyer lemons)
Step Two: add berries (frozen into ice cubes) into a pretty glass
Step Three: add agave or honey to taste (also acceptable: simple syrup)
Step Four: add lemon juice to taste
Step Five: add the water type of your choice (I'm pouring in bubbly water, here.)
Step the last: Stir, enjoy.
variations: more/less berries, mint leaves, booze.
The possibilities are endless.
