"This is the first time I've made ice cream ever, so kudos to Alton Brown for introducing this artisanal/gourmet ice cream! Merged what some of the other reviewers suggested.
2 1/2 cups of half and half
1 1/2 cup of heavy cream
Was lucky to find the Peppermint Flavored oil, which had a blend of sunflower oil and peppermint oil. Used 1 tsp of the brand "Simply Organic: Peppermint flavor". For the chocolate mint, I used Lindt Excellence Intense Mint Dark Chocolate bar, and chopped it up in thin slivers, it was fantastic! Reminded me of how Baskin Robbins does their Mint Chocolate Chip in a unique way, lots of great crunch in every bite. I will definitely be making this for dessert when guests come over!
