thanks everyone for the speedy replies (this is a good ice cream crowd!)
I called Margie's before I even posted and they said flat out "No!" (as if, oddly, they never carry it). I will call Oberweis tomorrow, I could swing by the Wicker Park store if need be and if they don't have it, I will call Homer's. My MIL says she actually prefers the kind with bits of candy in it, so that would be a big hit.
I do have a new-to-me electric ice cream maker. I had heavenly homemade peach sorbet at a party in July and the man who made the sorbet told me it was a breeze to make in his electric ice cream maker and he told me quite emphatically that I should not buy one new because you can always, always find them at the thrift stores for about $3. And sure enough, the following week I bought one at the Brown Elephant on Clark for $3 that had never even been taken out of the internal wrapping. Now I just need to break it in. But not just yet, and not with peppermint, I think I will start with something more seasonal or basic, like peach or vanilla.
anyhow, thanks again!
