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
Prepare the solution
Prepare a 10% or 5% water glass solution for preserving eggs.
Make lime water by mixing 1 pound of quicklime and 0.5 pound of table salt with 4 quarts of boiling water.
Preserve and store
Immerse eggs in either the water glass solution or the lime water and salt brine.
Store eggs in the solution for at least eight months.
Remove eggs from the solution when ready to use.

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.

Shared aroma: decanal (soap, orange peel).
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Water glass
- Forms a sealing layer over the eggshell that slows air and moisture exchange during storage.
- Quicklime
- Makes the lime water alkaline, which helps preserve the eggs in the solution.
- Table salt
- Adds salinity to the lime water brine, supporting the preserving solution.
The step that matters
Keep eggs fully immersed for the full storage period. Any part of the egg left above the liquid can allow air and microbes through the shell, spoiling the egg. Full immersion keeps the protective barrier intact across the long storage time.
