Preserved Ginger

Ingredients

Directions

Prepare the ginger

  1. Scald the ginger, wash it in cold water, and peel it.

  2. Cover the ginger with a weak syrup made from 1 pound of sugar in 6 pints of water and let it sit for 2 days.

Build the syrup

  1. Pour off the syrup and replace it with a stronger syrup, repeating this process 2 or 3 times until the syrup is very thick.

  2. To make the thick syrup, boil 12 pounds of sugar in 12 pints of water until it reaches the consistency of virgin honey.

Pack and seal

  1. Pack the ginger pieces in jars or glass bottles, filling them to the top with more thick syrup to eliminate air.

  2. Cork the bottles and seal the jars with pasted lids and parchment.

Ginger and sugar 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

Fresh ginger
Forms the main preserved pieces that absorb the sugar syrup and keep their flavor.
Sugar
Draws water out of the ginger and preserves it, giving the pieces sweetness and a firm texture.

The step that matters

Pour off and replace the syrup in stages. Moving the ginger into progressively stronger syrups lets sugar penetrate gradually. Jumping straight to a thick syrup can draw water out too fast, leaving the outside hard and the inside underpreserved.

Swap the ginger

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

  1. Cinnamonfits better
  2. Gingerthe original
  3. Nutmegfits less well
  4. Allspicefits less well

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