Lettuce Ginger

Ingredients

Directions

Prepare the lettuce

  1. Peel the outer coat of the lettuce stalks.

  3. Soak the cut lettuce in water with cayenne pepper and salt for two days.

  4. Strain the lettuce.

  5. Wash the lettuce in clean water.

Make the syrup and ginger

  1. Clarify an equal weight of fine loaf sugar.

  2. Soak the ginger in boiling water.

  3. Slice the ginger.

  4. Boil the ginger with the sugar for 15 minutes.

  5. Pour the hot syrup over the drained lettuce, reserving the ginger.

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

What each ingredient does

Tender lettuce stalks
Form the bulk of the preserve and, after soaking, become firm and crisp in the syrup.
Fine loaf sugar
Sweetens and, at high concentration, preserves the lettuce and ginger by drawing out water.
Ginger
Adds warm, pungent aroma and flavour that carries through the sugar syrup.
Lemon juice
Adds acidity that brightens the sweetness and balances the syrup.
Cayenne pepper
Adds heat and pungency to the lettuce during its soaking.

The step that matters

Repeated boiling of the syrup. Sugar must be concentrated gradually over several days so the syrup penetrates the lettuce without the pieces collapsing or the syrup crystallising. Each reboiling and pouring builds up sugar content and preservation, so the timing and temperature must be carefully controlled.

Swap the lettuce

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

  1. Capsicumfits better
  2. Carrotfits better
  3. Sweet potatofits better
  4. Lettucethe original

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