Ten.
Pounds.
Bill made some dutch oven blueberry cobbler over a fire (pictured with homemade vanilla ice cream):
Can you tell which is lime and which is peach? No? Me either. Which is why we always label jams.
I also made blueberry pie ice cream. It's vanilla ice cream with graham crackers layered with blueberry sauce. Yum. I'd make this again, but I would modify the blueberry sauce a bit to cook more water out of the berries. After only 7-10 minutes of boiling, most of the berries are still intact and freeze into little berry ice cubes. I think a longer cook, or even using some jam, would mitigate this.
Also, I might have to make my own graham crackers. We have a "no transfats in the house" rule, and it turns out nearly all graham crackers are made with partially hydrogenated oils. Except the organic ones. Which taste like cardboard.
After all this, plus freezing a bunch of berries and tons of munching, we've still got some left in the fridge.
