Roasted Persimmion – Rosemary Ice Cream

1 1/2 pounds fuju persimmons, about 7 – 8 medium
1 tablespoon melted butter
Pinch kosher salt or to taste
1 1/2 cups heavy cream
1 1/2 cups whole milk
1 sprig fresh rosemary
1 bay leaf
6 black peppercorns
5 large egg yolks (freeze egg whites for another use)
1/2 cup (minus 1 tablespoon) granulated sugar
1 tablespoon vanilla bean sugar
1/4 cup mild honey

Preheat oven to 400°F. Line a baking sheet with parchment paper. Have an ice bath ready.

Peel, core and slice persimmons into wedges. Toss the wedges with the melted butter and a pinch of salt. Arrange in a single layer on the lined baking sheet. Roast for 20 – 25 minutes, or until golden and tender. When persimmons can easily be pierced with a knife allow them to cool and and refrigerate overnight.

Meanwhile, place heavy cream, whole milk, rosemary sprig, bay leaf, if using and peppercorns, in a saucepan. Heat until bubbles form around the parameter of the pan, but do not boil. Turn off heat and allow to steep for about ½ hour and allow to cool. Once cool, whisk in the eggs, sugar, and honey.

Return the custard to a saucepan over medium-low heat and whisk constantly until it coats the back of a spoon, about 10 minutes or until an instant read thermometer registers 175° F. Remove from heat, transfer to a bowl and place in an ice water-bath, stirring frequently until cool. Cover with plastic wrap directly on the custard surface and refrigerate overnight.

When ready to churn, strain out the aromatics from the custard. Add 2 cups of the custard to a blender along with the persimmon wedges. Purée until very smooth, then stir back into the remaining custard. Churn in an ice cream maker according to manufacturer’s directions.
