Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Macaroon Custards
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the custard
Preheat the oven to 350°F (175°C).
In a bowl, whisk together the milk, eggs, sugar, and vanilla to make a custard.
Butter custard cups and fill them two-thirds full with the custard mixture.
Break the macaroons into small pieces and cover the top of each custard with them.
Bake and serve
Place the custard cups in a baking pan and surround them with boiling water.
Bake until puffed up in the center and firm.
Let cool for 3 minutes before turning out of the cups.
Serve very cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard and give it a firm, sliceable structure as they cook.
- Milk
- Forms the liquid base of the custard, providing moisture and a soft texture.
- Sugar
- Sweetens the custard and contributes to its browning at the surface.
- Macaroons
- Add a crisp, almond-sweet topping that contrasts with the soft custard.
The step that matters
Surround the cups with boiling water. The water bath insulates the custard so it heats gently. Without it, the eggs can cook too fast, causing overbaking, curdling, or a rubbery texture.
