Why it works: Lime and egg are a kitchen classic. They rank in the top 34% of all ingredient pairs, and cooks put them together in 1,658 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Preserving Eggs
Ingredients
Directions
Make the brine
Mix ½ gallon of fresh lime with 5 gallons of water gradually, adding 2½ gallons on the first day and the rest on subsequent days.
Stir in ½ gallon of coarse sea salt and mix well.
Stir the mixture two to three times a day for three days.
Preserve the eggs
Gently drop in 4 fresh eggs to preserve them.
Test the lime‑water strength by dropping a known fresh egg; if it floats, the lime is too strong.
Add more water until the egg sinks.

What each ingredient does
- Fresh lime
- Raises the alkalinity of the water, which slowly preserves the eggs by changing the egg's interior.
- Coarse sea salt
- Helps preserve the eggs and adds seasoning to the brine.
- Eggs
- The food being preserved; they absorb the alkaline, salty solution over time.
The step that matters
Testing the lime-water strength. If the lime is too strong, the solution can damage the eggs, so a test egg should be used to check strength. An egg that floats means the brine is too dense or too alkaline; adding water until the egg sinks gives a balanced solution.
