Why it works: Lime and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,289 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

To Preserve Eggs

Ingredients

Directions

Prepare the brine

  1. Dissolve the quick lime and salt in 1 gallon of boiling water.

  2. Let the mixture cool, then pour it over the eggs in a large vessel until they are covered.

  3. Use a stone jar of about six quarts for storage.

Pack the eggs

  1. Pack the eggs with the large end down, covering them tightly and placing them in a cool place.

  2. Alternatively, coat the eggs with butter or lard, then pack them in sawdust or bran, ensuring they do not touch each other.

  3. You can also coat the eggs with melted paraffin for preservation.

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

What each ingredient does

Quick-lime
Makes the liquid strongly alkaline, which helps preserve the eggs.
Salt
Adds saltiness and helps preserve the eggs by drawing out moisture.
Butter or lard
Forms a fat coating that seals the shell against air.
Paraffin
Forms a waxy coating that seals the shell against air.

The step that matters

Pack the eggs with the large end down. Keeping the large end down holds the air cell at the top, so the egg stays stable and the yolk stays away from the air space during storage.

Swap the lime

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

  1. Orangefits better
  2. Limethe original
  3. Raspberryfits about as well
  4. Coconutfits less well

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