Berry Lemonade

juice of 4 lemons
1/2 c sugar, or to taste
1 quart of water
assorted berry flavor jams

Juice lemons and run through a fine mesh sieve to remove any seeds. Add sugar and water and stir to combine. Chill completely. To serve put 1 tbsp. jam into each glass (I used raspberry and blackberry). Fill with ice and pour lemonade over the top. Add a swizzle stick for stirring and a lemon slice to garnish.
