Summer is almost here! Make this tasty fresh-squeezed lemonade to celebrate the last day of school. It's made with seltzer instead of water, so it's refreshing and fizzy. The lemon slices that float in the pitcher are optional of course, but they make it festive. For those of us who are out of school, or at least 21 or older, this also tastes good with vodka or gin added in. Serves 4.
3 small lemons
1/2 cup sugar
1-liter bottle unflavored seltzer water, chilled
