Eggs, Preserved

Ingredients

Directions

Prepare the eggs

  1. Smear the eggs with a solution of gum arabic and let them dry.

  2. Cover the dried eggs with powdered charcoal, bran, or sawdust.

  3. For boiling water preservation, plunge eggs in a net into boiling water for 20 seconds, then pack in bran.

Make the preserving solution

  1. To make a preserving solution, mix 3 pounds of quick-lime, 1 ounce of cream of tartar, and ½ pound of coarse sea salt in 5 to 6 quarts of boiling water.

  2. Once the solution is cold, cover the eggs with it and seal the vessel tightly.

Pack and store

  1. In a box or barrel, layer eggs with finely powdered salt, ensuring they do not touch.

  2. Press the salt down firmly and cover with a cloth and a tight lid.

  3. Store in a dry, cool place.

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. Egg + creamtop 24% of all pairs

    Shared aroma: acetic acid (sour, vinegar).

  2. Lime + creamtop 31% of all pairs

    Shared aroma: octanal (fat, soap).

    Shared aroma: decanal (soap, orange peel).

Egg and cream barely smell alike, yet cooks put them together in 42,166 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

Newly laid eggs
The eggs are the food being preserved, so their freshness determines the result.
Quick-lime
Creates a strongly alkaline solution that helps preserve the eggs over time.
Cream of tartar
Adds acidity to the preserving solution, helping to balance its alkaline chemistry.
Coarse sea salt
Draws moisture out and inhibits microbial growth in the preserving solution.
Powdered charcoal, bran, or sawdust
Forms a dry, absorbent coating that protects the eggs from air and contact.

The step that matters

Let the solution cool before adding the eggs. Adding eggs to a hot solution can cook or crack the shells and damage the contents, so the solution must be fully cold before the eggs are covered.

Swap the lime

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

  1. Vanillafits better
  2. Raspberryfits better
  3. Strawberryfits better
  4. Limethe original

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