Why it works: Vinegar and onion are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 18,226 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓
Boiled Sole
Ingredients
Directions
Prepare
Sprinkle salt lightly over the sole and place it in a dish with vinegar.
Poach
Put the fish and vinegar into enough hot white stock or water to cover the sole.
If using water, add the onion, salt, and peppercorns to it.
Let the sole stand in the liquid for 10 minutes, gradually heating it.
Simmer for 5 minutes or longer if the fish is thick.
Remove the sole, drain, and serve plain or with parsley sauce.

What each ingredient does
- Sole
- Is the main protein that turns firm and flaky as it cooks gently in the liquid.
- Vinegar
- Adds acidity that brightens the flavour of the mild fish.
- White stock or water
- Is the poaching liquid that cooks the fish evenly and gently.
The step that matters
Simmer for 5 minutes or longer if the fish is thick. Simmering rather than boiling keeps the liquid gentle so the delicate flesh cooks through without breaking apart or toughening. Thicker fish needs more time for the heat to reach its centre.
