Pears in Syrup

Ingredients

Directions

Prepare the pears

  1. Peel the pears and place them in a bucket of cold water mixed with 1 ounce of sulphite of soda per 7 gallons of water.

  2. If pears are not perfectly white after blanching, bleach them in sulphur fumes for 6 hours before blanching.

Blanch and cool

  1. Blanch the pears in the same water by placing them in a basket and slowly bringing it to a boil.

  2. Once softened, remove the basket and dip it in a cold water tank for 5 minutes.

Pack and process

  1. Pack the pears into cans or jars and cover with cold syrup, adding a few grains of vanilla for flavor.

  2. Process quart cans for 16 minutes and pint cans for 12 minutes in boiling water.

  3. Allow jars to cool in the processing tank for 10 minutes.

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

What each ingredient does

Pears
Form the main body of the dish, softening during blanching and processing into tender fruit.
Sulphite of soda
Helps keep the pears white during peeling and blanching by slowing browning.
Cold syrup
Adds sweetness and moisture, filling the cans and surrounding the fruit.

The step that matters

Blanching the pears. Blanching softens the fruit only enough to be packed, while the sulphite water protects its colour. Overcooking makes the pears mushy and underheating leaves them firm and prone to browning.

Swap the vanilla

The recipe marks vanilla as optional. How well each one fits the dish's main ingredients (pear, syrup):

  1. Vanillathe original
  2. Plumfits about as well
  3. Apricotfits less well
  4. Applefits less well

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