Like the black sapotes we've gotten in other weeks, canistels must go very soft to be fully ripe, and the fruit bowl of late has been looking like something out of a Peter Greenaway movie (I should have taken a picture). Of course, they rarely cooperate by ripening simultaneously, so I harvested the flesh of these as they ripened and froze it until they were all ready. Fortunately, Little Miss F liked the flavor of the canistel much moreso than the black sapotes (she's a big fan of mamey) so I had a willing assistant in preparing this.
I looked mostly at pumpkin flan (a/k/a flan de calabaza) recipes for inspiration, and after considering several variations went with the following (look, an actual recipe!):
- Flesh of 3 canistels (~1 cup)
- 4 eggs + 1 egg yolk
- 1 12-oz. can evaporated milk
- 1 14-oz. can sweetened condensed milk
- 2 tsp. vanilla extract
- 1 tsp. ground cinnamon
- 1 tsp. nutmeg (freshly grated)
- 3/4 cup sugar
Note that the color is almost entirely from the canistels, not the eggs. Then, make Thomas Keller proud - pour it through a strainer:
Next, the caramel. Put the 3/4 cup sugar into a saucepan over medium heat. Some recipes I read said stir constantly. Others said leave it alone until it starts to melt, then stir only occasionally. I eventually learned the latter instructions were the right ones. Just leave it be until the sugar starts to melt, then stir occasionally with a fork to incorporate the rest of the unmelted sugar. I stirred too early and ended up with big lumps that took longer to dissolve. After about ten minutes, you should have liquid (molten! be careful) golden-brown caramel.
