Peach Jelly

Ingredients

Directions

Prepare

  1. Pare, stone, and weigh the peaches. For every 3 pounds of peaches, use 1 lemon.

  2. Remove the thin yellow rind from the lemon.

Cook

  1. Cook the lemon rind with the peaches.

  2. Put the sugar and peach pulp in a pot over the fire and boil for 5 minutes, skimming off any white scum.

  3. Add the lemon juice and cook for 10 minutes, stirring constantly.

  4. If desired, add the chopped kernels from one-third of the peach pits instead of the lemon peel.

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

Peaches
Provide the main fruit flavor and the bulk of the jelly.
Sugar
Adds sweetness and, with the fruit and acid, helps the mixture thicken into a jelly.
Lemon
Adds acidity that brightens the fruit and supports setting.

The step that matters

Stir constantly during the final 10 minutes. As water evaporates, the sugar concentration rises and the mixture can scorch or stick to the bottom of the pot. Constant stirring spreads the heat evenly and keeps the jelly from burning before it reaches a set point.

Swap the peach

The recipe marks peach as optional. How well each one fits the dish's main ingredients (lemon, sugar):

  1. Orangefits better
  2. Limefits better
  3. Vanillafits better
  4. Peachthe original

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