Why it works: Arrowroot and lemon match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 553 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the custard
Scald the milk in a pot, stirring to prevent burning.
Beat the eggs in a bowl.
Pour the scalding milk over the eggs, stirring well.
Once cooled, add sugar, lemon essence or vanilla extract, and salt to taste.
Freeze
Pour the mixture into a deep tin pail or can that holds about 3 quarts.
Cover the can and place it in a larger water pail.
Pack ice around the tin can, mixing in 1 pint of salt, until it reaches near the top of the can.
Move the tin can around.
Lift the cover occasionally to scrape off frozen cream from the sides.
Continue for 15 to 20 minutes until frozen.
Serve
Serve immediately or keep cool for several hours covered with a flannel cloth.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the ice cream and carries the flavour and body.
- Eggs
- Thicken the custard base and add richness and structure as they set with heat.
- Sugar
- Sweetens the base and lowers the freezing point, keeping the ice cream softer.
- Cornstarch or arrowroot
- Thickens the base and helps give a smoother, less icy texture.
- Cream
- Adds fat for richness and a smoother, creamier mouthfeel.
The step that matters
Pour the scalding milk over the eggs, stirring well. Adding hot milk too fast or without constant stirring can scramble the eggs. Stirring while pouring tempers the eggs gently so the custard thickens smoothly.
Swap the arrowroot
The recipe marks arrowroot as optional. How well each one fits the dish's main ingredients (milk, cream, egg, sugar, lemon):
- Asparagusfits about as well
- Arrowrootthe original
- Sweet potatofits about as well
- Leekfits about as well
Fit is the average pairing score against milk, cream, egg, sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
