Sleeplessly I watch over the spring night, but no measure of guarding is enough to make it stay.
2 egg yolks
25 grams sugar
1 vanilla pod (or some essence)
Place milk and vanilla pod onto stove and bring to the boil. Whisk yolks and sugar and whisk in boiling milk. Return mix to gentle heat and stir constantly. Sauce is ready when glossy and just thick enough to coat the back of a spoon. To serve, drizzle around a tart.
