I like to make this for dinner guests:
3 cups fresh blueberries
3 cups fresh raspberries
Cup of strawberries, cut up
3 cups fresh blackberries or boysenberries
peel of a whole lime, cut into strips
peel of a whole lemon, cut into strips
1 cup of fresh mint leaves
In a saucepan, combine 3 c. of water with peels and bring to boil. Remove from heat, add mint leaves and steep for 30 minutes.
Strain, then put liquid back in saucepan with the sugar until boiling and sugar is fully dissolved.
Remove from heat again, cool or chill until at least room temp, and add about a tablespoon of juice from your lime and the lemon.
Gently mix liquid with the berries and chill in fridge for a few hours.
Best garnish? Sugared mint sprigs (easy to make, and amazingly tasty).
