01 - Preheat your oven to 300°F. Set 4 ramekins (6 oz each) in a deep baking dish.
02 - In a blender or food processor, combine persimmon pieces, 2 tablespoons sugar, and lemon juice. Blend until completely smooth.
03 - Divide the persimmon puree evenly among the ramekins, spreading it into a thin layer.
04 - In a saucepan, heat the cream and milk over medium heat until just steaming—do not boil. Remove from heat.
05 - In a mixing bowl, whisk egg yolks, 1/4 cup sugar, vanilla, and salt until pale and slightly thickened.
06 - Slowly pour the hot cream mixture into the yolks, whisking constantly to avoid curdling.
07 - Strain the custard through a fine mesh sieve into a pouring jug.
08 - Pour the custard gently over the persimmon puree in the ramekins.
09 - Pour hot water into the baking dish to reach halfway up the sides of the ramekins.
10 - Bake for 35–40 minutes, or until the custards are just set but still slightly wobbly in the center.
11 - Remove ramekins from water bath and cool to room temperature, then refrigerate at least 2 hours or overnight.
12 - Before serving, sprinkle 1 teaspoon sugar evenly over each custard. Use a kitchen torch to caramelize the sugar until it forms a crisp golden crust. Alternatively, broil under a hot grill for 1–2 minutes.
13 - Let the brûlée sit for 3–5 minutes before serving.
