Why it works: Lemon and peppermint match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,583 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Best Peppermint Drops
Ingredients
Directions
Prepare the syrup
In a bowl, combine the spring water and lemon juice.
In a deep copper drop-pan, mix a little of the water mixture into the sugar to form a paste thick enough to drop from a spoon.
Place the pan over a clear fire and stir until it just boils.
Flavor and shape
Remove from heat and add the oil of peppermint and more sugar to achieve the right thickness.
Color the drops with any desired color when adding the oil of peppermint.
Warm the mixture again without boiling.
Drop small amounts onto tin or pewter plates and let them cool.
Dry
Once cooled, transfer the drops to sheets of paper or sieves and place them in an oven to dry.

Lemon and sugar barely smell alike, yet cooks put them together in 53,532 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
- Fine loaf sugar
- Forms the bulk of the drops and sets into a firm, crisp candy as it cools.
- Lemon juice
- Adds acidity that helps prevent the sugar from turning grainy when cooked.
- Spring water
- Dissolves the sugar so it can be cooked into a smooth syrup.
- Oil of peppermint
- Provides the aroma and flavor that defines the drops.
The step that matters
Warm again without boiling. Once thickened, the mixture must stay below a boil; further boiling would overcook the sugar and make the drops harden too much or turn brittle and discolored.
Swap the peppermint
How well each one fits the dish's main ingredients (lemon, sugar):
- Cinnamonfits better
- Gingerfits about as well
- Marjoramfits about as well
- Peppermintthe original
Fit is the average pairing score against lemon, sugar. Candidates are from the same food group and used in at least 100 recipes.
