Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Ice Cream
Ingredients
Directions
Make the custard
In a clean kettle, combine 2 lbs sugar, 4 eggs, and vanilla extract. Stir well with an egg beater.
Add 4 quarts of cream and place the kettle on the fire. Stir constantly until it is about to boil.
Remove from heat and strain through a fine sieve into an earthen crock. Let it cool.
Freeze
Pour the mixture into a freezing can already filled with broken ice and salt.
Cover and turn the crank slowly and steadily until it cannot be turned any longer.
Open the can and remove the dasher. Scrape the hardened cream from the sides with a long-handled spatula.
Beat and work the cream until smooth. Close the can, drain off the water, and repack with fresh ice and salt.
Let it rest for an hour or two to harden.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Egg proteins thicken the custard as it cooks and add richness to the texture.
- Cream
- Fat gives the ice cream its smooth, rich body and slows the formation of large ice crystals.
- Sugar
- Sweetness, and it lowers the freezing point so the mixture stays softer and scoopable.
- Coarse sea salt
- Salt in the ice bath lowers its temperature so the mixture can freeze.
The step that matters
Stir constantly until it is about to boil. Eggs thicken as they heat, and if the custard gets too hot or sits unstirred it can curdle or scramble. Constant stirring spreads heat evenly so the base becomes smooth and thick without overcooking.
