Preserved Grape-fruit

Ingredients

Directions

Prepare the fruit

  1. Peel the rind off the grape fruit and place them in salted cold water.

  2. In a preserving kettle, cover the peeled grape fruit with warm water and boil slowly, changing the water every 10 minutes.

  3. Boil until the fruit can be easily pierced with a broom straw, then drain on a sieve.

  4. Cut into the stem-ends of the grape fruit with a sharp knife and remove the stringy pith.

Make the syrup

  1. In the kettle, combine 1½ pounds of loaf sugar and ½ cup of cold water for each pound of fruit, boil and skim the syrup.

  2. Once the syrup is clear, add the grape fruit and boil until transparent.

  3. Transfer the grape fruit to wide-mouthed jars and continue boiling the syrup.

Jar and seal

  1. When a little syrup cooled on a saucer jellies slightly, pour it over the grape fruit and let them cool in the syrup.

  2. Once both the fruit and syrup are cold, place a piece of paper wet in brandy in each jar and seal them air‑tight.

Sugar and brandy barely smell alike, yet cooks put them together in 11,939 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

Grape fruit
The main food being preserved; boiling turns its rind and pith tender and clear.
Loaf sugar
Forms the thick syrup that preserves the fruit and makes it transparent and sweet.

The step that matters

Boiling the syrup until the test sample jellies. Sugar must reach a concentration high enough to jell on cooling. Too little boiling leaves a thin syrup that spoils the fruit; too much makes it tough and over-thick.

Swap the grape

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

  1. Vanillafits better
  2. Apricotfits better
  3. Raisinfits better
  4. Grapethe original

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