Why it works: Egg and milk are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 88,785 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Frozen Custard
Ingredients
Directions
Prepare the custard
Break the eggs into a deep bowl.
In a porcelain kettle, heat the sweet milk until warm.
Stir in the sugar until dissolved, then bring to a full boil.
Slowly stir in the beaten eggs while the milk is boiling, stirring constantly until it thickens.
Pour the mixture into a large bowl or deep tin bucket and set it in cold water, stirring until the water warms.
Change the water and let it stand until ready to freeze.
Freeze and churn
Place the freezer in a tub filled with ice and salt, layering ice and salt alternately.
Pour the custard into the freezer and add your chosen flavor extract, stirring well.
Cover tightly and let it stand for a short time, then churn until hard, scraping the sides occasionally.
Wipe the top of the freezer before opening.

Milk and sugar barely smell alike, yet cooks put them together in 77,875 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard as they set when stirred into the hot milk, giving body and richness.
- Sweet milk
- Forms the liquid base of the custard that thickens and freezes into the texture.
- White sugar
- Sweetens the custard and lowers its freezing point, keeping it softer when churned.
- Ice and coarse sea salt
- Salt lowers the ice's temperature so the freezer tub gets cold enough to freeze the custard.
The step that matters
Stirring the beaten eggs into the boiling milk. Eggs scramble if added too quickly or left unstirred in hot liquid. Adding them slowly while stirring constantly lets the proteins thicken the custard smoothly instead of curdling it.
