What each ingredient does

Cod's roe
Forms the dish itself, setting firm and holding its shape when boiled.
Vinegar
Adds acidity to the poaching liquid, brightening the mild flavour of the roe.

The step that matters

Boil for 15 minutes, then lift the roe out and let it drain.. Boiling too long or too hard can toughen and crack the delicate roe membrane, leaving it dry and grainy. Timing the boil and draining it well keeps it moist and intact.
