Purin
Japanese Custard Pudding
A beloved Japanese konbini (convenience store) staple, this purin is a silky smooth, delicate custard pudding with a rich, slightly bitter caramel sauce. It's softer and less dense than a traditional French flan.

๐ง Ingredients
- 80 g Granulated sugar (for caramel)(About 1/3 cup)
- 1 tbsp Water (for caramel)(Optional, helps prevent crystallization)
- 3 Eggs(Large, at room temperature)
- 60 g Granulated sugar (for custard)(About 1/4 cup plus 2 tbsp)
- 400 ml Whole milk(About 1 2/3 cups)
- 1 tsp Vanilla extract

Prepare the caramel sauce. In a small, heavy-bottomed saucepan, combine the 80g of sugar and 1 tbsp of water (if using). Heat over medium heat without stirring. Swirl the pan gently as the sugar begins to melt and turn amber. Continue swirling until the caramel reaches a deep amber color, being careful not to burn it. Immediately pour the hot caramel evenly into the bottom of 6 individual ramekins (about 150-200ml capacity each). Swirl each ramekin to coat the bottom. Set aside to cool and harden.

Prepare the custard base. In a medium bowl, whisk together the 3 large eggs and 60g of sugar until well combined but not frothy. Gradually whisk in the 400ml of milk and 1 tsp of vanilla extract until smooth.
โฑ๏ธ 5 minutes - 3
Strain the custard mixture through a fine-mesh sieve into a pitcher or large measuring cup. This step is crucial for achieving a silky-smooth texture. Skim off any foam from the surface.
โฑ๏ธ 2 minutes - 4
Pour the strained custard evenly into the prepared ramekins, over the hardened caramel. Do not fill to the very top, leave a small headspace.
โฑ๏ธ 3 minutes - 5
Prepare for steaming or baking. Preheat your oven to 150ยฐC (300ยฐF) or prepare your steamer. Place the filled ramekins in a larger baking pan. Carefully pour hot water into the larger pan to come halfway up the sides of the ramekins (this is a bain-marie or water bath).
โฑ๏ธ 5 minutes - 6
Cook the purin. Carefully place the baking pan with the water bath into the preheated oven. Bake for 40-50 minutes, or until the custard is just set. It should still have a slight wobble in the center when gently shaken. If steaming, steam over medium-low heat for about 35-45 minutes, or until set.
โฑ๏ธ 40-50 minutes - 7
Cool and chill. Carefully remove the ramekins from the water bath and let them cool to room temperature on a wire rack. Once cooled, cover each ramekin with plastic wrap and refrigerate for at least 4 hours, or preferably overnight, to allow the flavors to meld and the custard to fully set.
โฑ๏ธ 15 minutes active time, plus chilling - 8
Serve. To unmold, run a thin knife or offset spatula around the edge of each ramekin. Place a serving plate on top of the ramekin and quickly invert. The purin should slide out onto the plate, with the caramel sauce pooling around it.

๐ก Pro Tips
- โStraining the custard is essential for a perfectly smooth, silky texture. Don't skip this step!
- โUse medium-low heat for both caramelization and cooking the custard to prevent burning and ensure even cooking.
- โThe Japanese purin is intentionally softer and more delicate than a French flan or crรจme caramel. Aim for a slight jiggle when done.
- โEnsure eggs and milk are at room temperature for a smoother, more homogenous custard.
- โFor a cleaner unmolding, ensure the caramel has fully hardened and the custard is thoroughly chilled.
