Crème Anglaise

Combine the whole milk and heavy cream in a medium heavy-bottomed saucepan. Split the vanilla bean lengthwise with a sharp paring knife and scrape out the seeds — drag the back of the knife along the cut face to lift the fine black paste. Add both the seeds and the empty pod to the milk. Heat over medium heat until the mixture reaches a full simmer — you will see the vanilla seeds dispersing into tiny black dots throughout the milk. Turn off the heat, cover the pot, and let the vanilla infuse for 15 minutes. This off-heat infusion extracts the full aromatic complexity of the vanilla without cooking out the volatile top notes that make it smell floral rather than simply sweet. If using extract, add it after the anglaise is cooked and cooled to 60°C — heat destroys the delicate top notes of good extract.

While the milk infuses, place the egg yolks, caster sugar, and pinch of salt in a large heatproof bowl. Whisk vigorously for 2–3 minutes until the mixture reaches the ruban (ribbon) stage — a thick, pale, fluffy foam that falls from the whisk in a wide, slow ribbon that sits on top of itself for two seconds before dissolving. This step partially dissolves the sugar and coats the yolk proteins with a sugar barrier that raises their coagulation temperature, giving you a wider window before the anglaise scrambles on the heat. The mixture will go from a deep orange-yellow to a pale, creamy yellow as you incorporate air. Do not skimp on the whisking — under-developed yolks are the primary cause of grainy anglaise.

This is the critical step that separates successful anglaise from sweet scrambled eggs. Remove the vanilla pod from the milk. With one hand whisking the yolk mixture constantly, use the other to slowly ladle or pour the hot milk into the yolks — start with just a small splash (about 60ml / ¼ cup) and whisk it in completely before adding more. This gradual addition raises the temperature of the yolks slowly, preventing them from cooking on contact with the hot milk. Add the milk in three additions over 30 seconds of whisking. Once you have incorporated about half the milk, you can pour the remaining milk in a thin, steady stream while whisking. Pour everything back into the saucepan. The mixture will be warm, thin, and faintly foamy on top — this foam dissipates as you cook.

Cook the custard over medium-low heat, stirring constantly with a wooden spoon or silicone spatula, reaching every corner and edge of the pan. This is not a step you can walk away from. The anglaise is done when it reaches 77–82°C (170–180°F) and nappe-coats the back of the spoon — a finger drawn through the coating leaves a clean, distinct line that does not run or fill in. At 83°C the egg proteins begin to scramble rapidly. Use a thermometer if you are new to this technique. Once done, immediately strain through a fine-mesh sieve into a clean bowl sitting over an ice bath. Stir to cool rapidly — the anglaise must drop below 60°C within 10 minutes. Serve warm alongside warm puddings or cakes, or chill completely to pour cold over ice cream as a pouring custard.
