Punch a LA Ford

Ingredients

Directions

Prepare the peel

  1. Peel the lemons very thin.

  2. Place the lemon peels in a large bowl.

  3. Add the sugar and stir with a wooden spoon for about 30 minutes to extract the essential oil.

  4. Pour boiling water over the peels and stir until the sugar dissolves.

Make the juice

  1. Cut the lemons in half and squeeze out the juice, straining out the seeds.

  2. Pour boiling water over the lemon juice and let it sit.

  3. Strain this water into the bowl with the peels.

  4. Add half the quantity of lemon juice to the mixture.

Finish and bottle

  1. Taste the mixture.

  2. Adjust the acidity or sweetness as needed.

  3. Strain the mixture until clear.

  4. Add 1 pint of cognac and 1 pint of old rum for every 3 quarts of punch.

  5. 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
Supply the acidity and the aromatic oil from the peel that flavours the punch.
Lump sugar
Sweetens the punch and, stirred with the peels, draws out their essential oil.
Cognac brandy
Adds spirit strength and a warm, fruity aroma to the punch.
Old rum
Adds spirit strength and deeper caramel-like flavour to the punch.

The step that matters

Extracting the peel oil with sugar. Stirring sugar into the lemon peels rubs the oil out of the peel's surface cells. Peeling too thick adds bitter white pith, and skipping the stirring leaves the punch with a flat, weak citrus aroma.

Swap the lemon

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