Ingredients

Directions

Prepare

Macerate

  1. Bruise the ginger and tie it in a muslin bag with the lemon ends and seeds.

Sugar and ginger barely smell alike, yet cooks put them together in 14,054 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

Marrow
Forms the bulk of the preserve and softens into a tender, spreadable body as it cooks.
Lump sugar
Sweetens the preserve and draws moisture out of the marrow, helping it thicken and set as it cooks.
Lemons
Add acidity that brightens the flavour and helps the preserve set, while their pectin-rich seeds and ends are cooked in the bag.
Whole ginger
Adds warm, aromatic spice that infuses the syrup during the long standing and boiling.

The step that matters

Boil gently for 3 hours. Gentle heat lets the marrow soften and the sugar concentrate slowly, so the preserve thickens without scorching on the bottom of the pan. A hard boil can burn the sugar and toughen the fruit.

Swap the lemon

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

  1. Lemonthe original
  2. Orangefits about as well
  3. Limefits less well
  4. Vanillafits less well

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