  2. Let the mixture sit for 20 minutes, stirring slowly to dissolve the sugar and infuse the flavor.

  3. Remove the lemon peel and let the toddy stand for another 20 minutes.

Serve

  1. Add a large lump of ice and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Old antigua rum
Provides the base spirit and most of the flavor of the drink.
Lump sugar
Adds sweetness that balances the strong alcohol and lemon flavor.
Lemon peel
Releases aromatic oils into the liquid, adding citrus fragrance and flavor.

The step that matters

Let the mixture sit and infuse. Sugar dissolves and lemon oils move into the liquid only with time and gentle stirring. Rushing this step leaves the drink sharp, gritty with undissolved sugar, and less rounded in flavor.

Swap the lemon

How well each one fits the dish's main ingredients (rum, sugar):

  1. Vanillafits better
  2. Pineapplefits better
  3. Bananafits better
  4. Lemonthe original

Fit is the average pairing score against rum, sugar. Candidates are from the same food group and used in at least 100 recipes.
