To Preserve Eggs

Ingredients

Directions

Make the lime liquid

  1. Combine the quick lime and salt in a large vessel.

  2. Slake the mixture with 1 gallon of boiling water.

  3. Wait until it bubbles and is thick as cream.

  4. Once cool, pour off the clear liquid on top and drain it.

Soak and pack the eggs

  1. Pour the liquid over the eggs, ensuring they are fully covered.

  2. Pack eggs in a jar with layers of salt, large end down, and cover with a thick layer of salt.

  3. Dip eggs in boiling water for half a minute.

Coat and store

  1. Pack eggs in sawdust.

  2. Brush eggs with dissolved gum arabic.

  3. Pack eggs in powdered charcoal.

  4. Smear eggs with butter or lard.

  5. Pack eggs in bran or sawdust.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

  1. Lime + lemontop 1% of all pairs

    Shared aroma: beta-phellandrene (minty, terpene).

  2. Lemon + eggtop 19% of all pairs

    Shared aroma: (e,e)-2,4-decadienal (fatty, deep fried).

  3. Lime + eggtop 34% of all pairs

    Shared aroma: decanal (soap, orange peel).

Lemon and egg barely smell alike, yet cooks put them together in 44,316 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Quick-lime
Forms an alkaline liquid that helps preserve the eggs during soaking.
Salt
Draws out moisture and slows spoilage in the packing layers.

The step that matters

Keep every egg fully submerged. Any egg left partly uncovered by the liquid can spoil or dry out, so the eggs must stay completely covered throughout soaking.

Swap the lime

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

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

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

“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
