Boiled Cod’s Roe
Ingredients
Directions
Prepare
Wash the roe well in cold water, then tie it up in a piece of muslin.
Boil and drain
In a saucepan, combine 1 pint of water, vinegar, salt, and peppercorns.
Bring the mixture to a boil, then add the roe.
Boil for 15 minutes, then lift the roe out and let it drain.
Serve
Place it on a hot dish and pour sauce over it, adding lemon juice and cayenne.
Alternatively, garnish the roe with parsley and scalloped lemon, serving the sauce separately.

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.
