Prepare
Rub the bottom of a frying pan with butter.
Pour in boiling water and add salt and vinegar.
Let the water stay hot but not boil.
Poach the eggs
Carefully crack the eggs into the water.
Let the eggs cook until set on the bottom.
Loosen the eggs with a spatula to avoid overcooking.

Place the toast on warm plates, dot with butter.
Remove the eggs from the pan with a skimmer and place on the toast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set protein forms the poached body and gives the dish its main structure.
- Vinegar
- Acidity helps the egg whites set more quickly and hold together in the water.
- Bread
- Toasted base that gives a crisp, browned contrast to the soft egg.
- Butter
- Adds richness and flavour to the pan and the finished toast.
The step that matters
Let the water stay hot but not boil. At a rolling boil the water churns and tears the delicate egg whites apart. Gentle heat lets the whites set around the yolk into a neat shape.
