Peach Marmalade

Ingredients

Directions

Cook the peaches

  1. Place the peaches in a pot and heat slowly, stirring frequently to prevent burning.

  2. After 45 minutes of boiling, add the sugar and boil for 5 minutes, skimming constantly.

Finish and jar

  1. Add the chopped peach stone kernels and lemon juice, then cook for an additional 10 minutes.

  2. Pour the mixture into small jars or jelly glasses.

Sugar and lemon 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 body, flavour and pectin-bearing pulp that thickens the marmalade.
Sugar
Sweetens the marmalade and helps it set into a thick, spreadable texture.
Lemon juice
Adds acidity that brightens the flavour and supports gel formation.
Peach stone kernels
Contribute a subtle almond-like aroma to the marmalade.

The step that matters

Skimming while the sugar boils. Sugar is added to fruit that is already boiling, and foam and scum rise to the surface. Skimming constantly keeps the marmalade clear and free of off-flavours, and the boil must be kept going so the mixture can reach a set.

Swap the lemon
