Silky Stovetop Vanilla Custard

By Sprig Originals ✓ · cooked up in Sprig

A classic stirred vanilla custard, thick enough to coat a spoon and pour in slow ribbons over fruit, cake or pie. The whole trick is heat control: warm the dairy, temper the yolks slowly, then cook to a specific temperature and a visible thickening cue before straining it smooth. Made with five ingredients and a whisk, it tastes like the humble diner-case dessert it's descended from — only better, because you can see the vanilla seeds in it.

Ingredients

• 1 1/2 cups whole milk
• 1/2 cup heavy cream
• 1 vanilla bean, split lengthwise (or 2 tsp vanilla bean paste / pure vanilla extract)
• 5 large egg yolks
• 1/2 cup granulated sugar
• 1/8 teaspoon fine sea salt
• 1 tablespoon unsalted butter, cold, cut in 2 pieces

• 2 teaspoons cornstarch

• fresh berries, sliced peaches or roasted plums
• grated nutmeg or shaved dark chocolate
• buttery cookies or pound cake, for dipping

Instructions

1. Set up before you turn on the heat: place a fine-mesh strainer over a heatproof bowl (metal is best) and set that bowl inside a larger bowl holding a few inches of ice water. Have a silicone spatula and an instant-read thermometer within reach. Custard moves fast at the end and there is no time to hunt for equipment.
2. Pour the milk and cream into a heavy 2-quart saucepan. Scrape the seeds from the split vanilla bean into the pan with the tip of a knife and drop in the pod too (if using paste, add it now; if using extract, hold it back until step 8). Warm over medium heat, stirring occasionally, until the surface steams and small bubbles ring the edge, 160–175°F, about 5 minutes. Do not let it boil. Slide the pan off the heat, cover, and steep 10 minutes.
3. Meanwhile, whisk the egg yolks, sugar, and salt in a medium bowl for about 1 minute, until the mixture lightens in color and falls from the whisk in a thick ribbon. If you want a firmer, spoonable custard rather than a pouring sauce, sift the cornstarch in now and whisk until no lumps remain.
4. Temper the yolks: whisking the yolk mixture constantly with one hand, ladle in about 1/2 cup of the hot dairy in a thin, steady stream. Repeat with a second 1/2 cup. The bowl should now feel warm, not hot. Never dump hot liquid in all at once — that is exactly how you get scrambled egg.
5. Pour the tempered yolk mixture back into the saucepan with the remaining dairy and whisk to combine.
6. Cook over medium-low heat, stirring constantly with the spatula and scraping the bottom and corners of the pan in a slow figure-eight, 4 to 7 minutes. The custard will thin slightly, then start to thicken. Keep the heat gentle; if you see any steam wisps turning into simmering bubbles, pull the pan off the heat for 15 seconds and keep stirring.
7. Watch for the doneness cue: the custard reaches 175–180°F (up to 185°F if you used cornstarch, which needs a bubble or two to activate), it visibly coats the back of the spatula, and when you drag a finger through that coating the line holds clean for a full 3 seconds without flooding back. That is the moment. Take it off the heat immediately.
8. Pour the custard through the strainer into the chilled bowl at once, pressing gently with the spatula; discard the vanilla pod and any bits caught in the mesh. Stir in the cold butter and, if using, the vanilla extract. Stir over the ice bath for 2 minutes to stop the cooking, until the custard drops below about 120°F.
9. Serve warm as a pouring sauce, or press a piece of plastic wrap directly onto the surface (this prevents a skin) and refrigerate at least 3 hours, until cold and thickened. Whisk briefly before serving, then spoon over fruit or into small glasses with a grating of nutmeg.
