I just got a new Cuisinart ice cream maker. Followed the recipe for strawberry ice cream, but used same amount of pureed peach. I processed the cut up ripe peaches well in my food processor and added it to the mix. The ice cream came up tasty,but the peaches in there are grainy. Should I have used my blender to get the peaches smoother? Or should I have let the peaches get a bit overripe before using? I love Breyer's peach ice cream when they have it and wonder how I can get that same peach texture. Any ideas out there?
