David Lebovitz’s Pumpkin Ice Cream.
Thanks to a reference from @ maccrogenoff.
This came out exactly as I hoped - rich with plenty of pumpkin flavor. I used 2 teaspoons cognac, and strained it twice, the second time after the final blend.
I’m not sure it’s anything I would make outside of the holidays, but it’s fun and very seasonal. Thus far (before an overnight cure) it gets a solid thumbs up from all tasters.
