Why it works: Lemon and egg are a kitchen classic. They rank in the top 19% of all ingredient pairs, and cooks put them together in 44,316 recipes. Both carry (e,e)-2,4-decadienal, which smells fatty, deep fried. The science ↓
To Preserve Eggs
Ingredients
Directions
Make the brine
In a large vessel, combine quicklime and coarse sea salt.
Stir the mixture with 1 gallon of boiling water until it thickens like cream.
Once cool, pour off the clear liquid.
Cure the eggs
Use a stone jar that holds about 6 quarts for best results.
Drain this liquid and pour it over the eggs, ensuring they are fully covered.

Shared aroma: (e,e)-2,4-decadienal (fatty, deep fried).
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
- Quicklime
- Raises the alkalinity of the liquid, which slowly transforms the egg white and yolk during curing.
- Coarse sea salt
- Adds salinity that helps preserve the eggs and supports the curing process.
- Eggs
- The food being preserved; the curing liquid gradually sets the whites and yolks.
The step that matters
Fully covering the eggs with the clear liquid. Any egg left above the liquid can spoil, because air exposure allows microbial growth. Keeping every egg submerged keeps the alkaline, salty environment uniform and protective.
