Why it works: Vinegar and egg are a kitchen classic. They rank in the top 33% of all ingredient pairs, and cooks put them together in 12,922 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓
Poached Eggs
Ingredients
Directions
Poach
Place a deep frying pan or low, wide saucepan with 2 quarts of water over the heat.
Add ½ teaspoon salt and ½ tablespoon vinegar; bring to a boil.
Crack an egg and let it drop into the boiling water.
Repeat for the remaining eggs.
Move the pan to the side of the stove to stop boiling.
Once the egg whites are firm, carefully remove the eggs with a skimmer.
Serve
Cut the eggs into a round shape with a cake cutter and place them on buttered toast.

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: acetic acid (sour, vinegar).
Vinegar and egg barely smell alike, yet cooks put them together in 12,922 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
- Eggs
- Egg whites set in the hot water, forming the soft, tender poached body of the dish.
- Vinegar
- Acidity helps the egg whites coagulate more quickly and hold together in the water.
The step that matters
Moving the pan off the heat before adding eggs. Simmering or boiling water is too turbulent and tears the egg whites apart. Holding the water just below a boil lets the whites set gently around the yolk.
