Why it works: Vinegar and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and 18,203 recipes mention both. Both carry acetic acid, which smells sour, vinegar. The science ↓
The recipe
Ingredients
Contains: egg (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Make the pickling solution
Combine vinegar, water, salt, sugar, and peppercorns in a pot and bring to a simmer over medium heat.
Stir regularly while heating so that the sugar on the bottom of the pot doesn't burn. Simmer until the sugar and salt are fully dissolved.
Remove the pot from the heat and allow the pickling solution to cool to room temperature.
Cook and peel the eggs
Bring a large pot of water to a boil.
Gently lower the eggs into the boiling water with a ladle. Wait for the water to return to a boil and then boil the eggs for an additional 12 minutes.
Drain the hot water from the eggs and transfer the eggs to ice-cold water to stop the cooking.
Crack and peel the eggs, removing the membrane between the egg and the shell.
Layer and pickle
Cut the onions into 5 mm thick rings.
Place a layer of onions in a large, non-reactive container, then arrange a layer of eggs on top. Continue layering until all eggs and onions are used.
Pour enough pickling solution over the layers to fully cover the eggs and onions. Refrigerate for two weeks before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Are the main food being preserved, taking on the sour, spiced flavour as they soak.
- Malt vinegar
- Provides the acidity that preserves the eggs and gives the pickle its sharp flavour.
- Granulated white sugar
- Balances the sharpness of the vinegar with sweetness.
- Onions
- Add sharp, savoury flavour that mellows as they soak in the brine.
- Whole black peppercorns
- Add aromatic, mildly spicy flavour to the pickling solution.
The step that matters
Transfer the eggs to ice-cold water right after boiling. Plunging the eggs into ice water stops carry-over cooking, which would otherwise leave a greenish ring around the yolk and make the eggs rubbery, and it also makes the shells easier to peel.
