Ingredients

Directions

Prepare the marrow

  1. Peel and core the marrow, then cut it into large pieces.

  2. Sift sugar over the pieces and let them stand overnight.

  3. In the morning, cut the marrow into pieces at least 1 inch thick.

Cook

  1. Place the pieces in a preserving pan with ginger, Cayenne pods, lemon rind, and lemon juice.

  2. Boil for 20 minutes, or until the marrow is perfectly clear.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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 becomes translucent as it cooks in syrup.
Sugar
Draws moisture out of the marrow and, once dissolved, sweetens and helps preserve the pieces.
Lemon juice
Adds acidity that brightens the flavour and supports setting.

The step that matters

Boil until the marrow is perfectly clear. Marrow flesh is pale and watery when raw. Cooking it in sugar syrup slowly replaces its water with syrup, which makes the pieces translucent. Stopping too early leaves them opaque and soft, and boiling too long can make them tough or sticky.

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.
