Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

Ingredients
Directions
Make the custard
Boil the vanilla bean in the milk, then strain and let it cool.
Add the loaf sugar to the cooled milk.
Beat the egg yolks until light and stir them into the mixture.
Heat the mixture over low heat for 5 minutes until it thickens into a custard, being careful not to boil.
Add the isinglass and cream
Dissolve the isinglass in 1 pint of water, ensuring half the water evaporates.
Once the custard is cold, mix in the dissolved isinglass thoroughly.
Whip the cream until frothy, then gently fold it into the custard.
Mould and set
Line the bottom of a mold with white paper and the sides with lady-fingers or sponge cake.
Pour the custard into the mold, cover with white paper, and set it on ice mixed with coarse salt.
Let it set for at least 3 to 4 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard and add richness as they set when gently heated.
- Isinglass
- Gelatin-like setting agent that firms the custard so it holds its shape when chilled.
- Rich cream
- Whipped and folded in to add lightness and fat for a creamy, airy texture.
- Milk
- Forms the liquid base of the custard, carrying the sugar and yolks.
The step that matters
Heating the custard gently. Egg yolks thicken through gentle heat, but boiling can curdle them and leave a grainy custard. Keep the heat low and stop as soon as it coats a spoon.
