A couple of weeks ago I bought a ton of peaches from Costco and they just weren't great. Good flavor, but the consistency wasn't fabulous and they were ripening way too quickly. So I chopped them up and tossed them in the freezer to deal with later.
To make the ice cream, I just let them soften for 10 or 15 minutes and then threw them in the food processor. Once they were mostly processed I added in a mixture of cream and sugar (about a cup of cream and 2/3 cup of sugar, though it definitely depends on the type and amount of fruit.)
Ten minutes later, voila, we have peach ice cream.
So good. And it's going fast.
