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 ↓
Ice Cream
Ingredients
Directions
Make the base
Wet the arrowroot with a little cold milk and add it to the boiling milk.
Sweeten the mixture with white sugar and add the grated lemon peel.
Boil the mixture, then strain it into the quart of cream.
Freeze
When the mixture is partly frozen, add the lemon juice.
To freeze, mix equal parts of snow and salt in a tub and place the cream in a tightly covered tin pail.
Turn the pail half round and back again with one hand for about 30 to 45 minutes, mixing the frozen part with the rest several times.
Cover the freezer tightly with snow and salt until ready to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Arrowroot
- Thickens the milk mixture so the finished ice cream is smooth and creamy.
- Thick cream
- Adds fat, which makes the ice cream rich and soft in texture.
- White sugar
- Sweetens the mixture and lowers its freezing point so it stays softer.
- Lemon juice
- Adds acidity for a bright, tart flavour.
The step that matters
When the mixture is partly frozen, add the lemon juice.. Adding acid to a fully set base can cause curdling or separation and uneven texture. Adding it once the base is partly frozen helps keep the mixture smooth and evenly flavoured.
Swap the arrowroot
How well each one fits the dish's main ingredients (milk, lemon, cream, sugar):
- Arrowrootthe original
- Potatofits about as well
- Sweet potatofits about as well
- Asparagusfits less well
Fit is the average pairing score against milk, lemon, cream, sugar. Candidates are from the same food group and used in at least 100 recipes.
