Crab Apples Preserved

Ingredients

Directions

Prepare

  1. Select good sound crab apples and remove the ends, leaving the stems on.

  2. Wash the apples and place them in a preserving kettle with enough water to cover them.

Cook the apples

  1. Bring the water to a boil, gently pushing the apples down to keep them submerged.

  2. Once the skins begin to crack, remove the apples and place them on a dish.

Make the syrup

  1. For each pint of juice, add 1½ pounds of sugar and boil for 15 to 20 minutes, skimming until clear.

  2. Return the apples to the juice in batches and boil for 15 minutes.

  3. Remove the apples again and add the remaining fruit to the juice, boiling for the same amount of time.

Jar and seal

  1. Fill jars with the apples to the top.

  2. Boil the remaining juice for about 10 minutes and pour it over the fruit in the jars.

  3. Seal the jars tightly and store them away.

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

What each ingredient does

Crab apples
The main fruit, cooked whole so it holds its shape in the syrup.
Sugar
Sweetens the juice and helps preserve the fruit by drawing out water.

The step that matters

Removing the apples when the skins begin to crack. Boiling the fruit too long breaks down the flesh and leaves it mushy. Lifting the apples out at first cracking keeps them whole, and they finish cooking later in the hot syrup.

Swap the apple

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

  1. Raisinfits better
  2. Lemonfits better
  3. Vanillafits better
  4. Applethe original

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