I cut the sugar by about half and still found this recipe a bit sweet. I also didn't understand the butter, but the end result was good. Instead of the vanilla bean, I used two teaspoons plus a dash of vanilla extract. I would add another half teaspoon to teaspoon if I make it again.
This ice cream recipe is amazingly rich. I used good vanilla extract instead of vanilla bean. I'll make it again with the usual - fresh Edgefield county peaches. I'll drive a hundred miles out of my way to get them from that area and it makes all the difference.
This ice cream was outstanding. We had it with peach pie for a special ending to Father's Day Sunday Lunch. I would make this again. The butter was an interesting addition to the recipe that I have never heard of before but the ice cream was all that it should be!
