Vegetable Marrow Preserved

Ingredients

Directions

Prepare the marrow

  1. Soak the vegetable marrow in a mixture of salt and water for 12 hours.

  2. Pare the vegetable marrow.

  4. Cut the marrow into small, thick, square pieces.

  5. Boil the pieces in water until tender.

  6. Strain the boiled pieces.

Make the syrup

  1. Make a syrup by boiling powdered sugar with sliced lemons and whole ginger.

  2. Add the vegetable marrow to the cold syrup.

  3. Let the mixture stand for 2 days.

  4. Pour off the syrup.

  5. Add more sugar to the syrup.

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

Vegetable marrow
Forms the bulk of the preserve and becomes tender and translucent as it cooks in the syrup.
Powdered sugar
Sweetens the preserve and, when concentrated by boiling, thickens the syrup and helps preserve the marrow.
Lemons
Add acidity and bright flavor that balances the sweetness of the syrup.
Whole ginger
Adds aromatic warmth to the syrup.
Coarse sea salt
Draws water out of the marrow during the initial soak, firming its texture.

The step that matters

Repeated boiling of the syrup. Sugar must be concentrated by several boils until the syrup is strong and transparent. Too little boiling leaves a thin syrup that will not preserve the marrow or give it a clear, glossy look.

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.
