Why it works: Cognac brandy and rum share more aroma than cooks usually use. They rank in the top 1% of all ingredient pairs, and cooks put them together in 68 recipes. Both carry 2-methoxy-4-propylphenol, which smells allspice, anise. The science ↓
Punch a LA Ford
Ingredients
Directions
Prepare the peels
Peel the lemons very thin and place the peels in an earthen vessel.
Add the lump sugar and stir together with a wooden spoon for about 30 minutes to extract the essential oil.
Pour boiling water over the peels and stir until the sugar dissolves.
Make the juice and base
Cut the lemons in half.
Squeeze out the juice, straining out the seeds.
Pour boiling water over the squeezed lemons.
Strain this water into the earthen vessel.
Add half the quantity of lemon juice to the vessel.
Taste the mixture.
Adjust the acidity or sweetness by adding more lemon juice or sugar as needed.
Finish and bottle
Strain the mixture until clear.
Add 1 pint of cognac brandy and ½ pint of old rum for every 3 quarts of the mixture.
Bottle the punch immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemons
- Their peel supplies aromatic oil and their juice supplies the sharp acidity that balances the punch.
- Lump sugar
- Sweetness that balances the lemon acidity and draws oil out of the peel when stirred.
- Cognac brandy
- Adds alcohol and warm aroma, and helps preserve the punch.
- Old rum
- Adds depth and aged sweetness, rounding out the flavour alongside the brandy.
The step that matters
Adjusting acidity and sweetness after tasting. Lemon juice strength varies, and the sugar and acid must balance before the spirits are added. Once brandy and rum are in, the mixture is harder to correct, so tasting and adjusting first matters.
