Black raspberries grow really well here and they are really in season right now. A friend of mine invited me over to pick some a while ago and I also have bought some from the farmer's market. They are so ripe and fresh that cooking them seems to be a shame so I have a few ways I like to use them (other than stuffing my face) that let their ripe freshness shine.
I made a tart from a recipe on Epicurious.com the Raspberry Sour Cream Tart.
I made it just as written (with a few flubs on the crust, but all was well in the end) and it was extremely delicious. The lemon juice in the cream cheese and sour cream filling gives it a lovely tartness that goes well with the berries. Its also very easy and delicious to make your own graham cracker crust. I didn't have a food processor like in the recipe, so I just put the crackers in a plastic bag and crushed them with a rolling pin. YUM.
The other think I've been doing with the berries is concocting drinks that involve berries.
Here is my fresh black raspberry cocktail.
4 cans ginger ale or a bottle of your favorite dry white wine
24 or so berries
Wash and place berries in a small bowl or plate. Smash them with a fork until they resemble jam. Pour 4 wine glasses with your ginger ale or white wine. Pour an equal amount smashed berries into each glass and serve. If you really hate seeds you can strain the smashed berry to get rid of them, though it looks prettier with the whole bits of berry swirling around the glass.
I'm actually drinking one right now. Its delicious!
