Blackberry Lemonade

6 lemons
2 cups water
1 cup sugar
1/2 cup fresh blackberries*
lemon slices for garnish

With a vegetable peeler remove zest from 4 lemons* and squeeze enough juice from these and remaining 2 lemons to measure 1 cup.

In a saucepan boil 1 cup water with 1 cup sugar, stirring, until sugar is dissolved. Add zest, lemon juice, and remaining 1 cup water and cool.

In a food processor or blender puree blackberries and stir into lemonade. Pour blackberry lemonade through a sieve into a pitcher and chill. Chill the lemonade, covered, at least until cold and up to 2 days.

Serve lemonade over ice in tall glass, garnished with lemon slices.
Makes about 1 quart.
