To Preserve Cucumbers

Ingredients

Directions

Prepare the cucumbers

  1. Select cucumbers free from seeds; use small ones whole and cut large ones into quarters, removing seeds and soft parts.

  2. Soak cucumbers in a jar with strong salt and water, weighted down with a cabbage leaf, in a warm place until they turn yellow.

  3. Wash cucumbers and place them in fresh water with a little salt and a fresh cabbage leaf.

  4. Cover and heat without boiling.

  5. If cucumbers are not a fine green, change the water and heat again.

  6. Once they are a good green, remove from heat and let cool.

Make the syrup

  1. Combine sugar and water in a pot.

  2. Skim the mixture clean.

  3. Add the end of a lemon and scraped ginger.

  4. Cook until thick.

  5. Once syrup is cold, dry the cucumbers.

  6. Immerse them in the syrup every two to three days.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cucumbers
Form the pickle itself; salting and heating firm and colour them before the syrup is added.
Sugar
Sweetens the syrup and, as it thickens, preserves the cucumbers.
Strong salt
Draws water out of the cucumbers and helps firm their texture during soaking.
Ginger
Adds a warm, aromatic flavour to the syrup.
Lemon
Adds acidity and brightness to the syrup.

The step that matters

Heating the cucumbers to a good green. Heating must stay below boiling, and the cucumbers should be checked for colour. Boiling can soften them and break their structure, while water changes remove the dull yellow that comes from soaking, leaving a firm, bright green pickle.

Swap the cabbage

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

  1. Broccolifits better
  2. Radishfits better
  3. Arrowrootfits better
  4. Cabbagethe original

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