Gravad rainbow trout
Gravad rainbow trout is a classic that is surprisingly simple to make yourself on your put-and-take catch. You only need salt, sugar and dill — and patience. Important: because gravad fish is never cooked through it must be frozen for 2–3 days (see below).
How to do it
- Freeze first the fillets for at least 2–3 days and thaw them — or plan to freeze after curing. This deals with parasites.
- Mix salt and sugar. Rub the mix into the flesh side of both fillets.
- Scatter on plenty of dill (and optional white pepper).
- Lay the fillets against each other, flesh to flesh, in a dish or a bag.
- Put a light press on top (for example a plate with a tin) and keep it cold for 1–2 days. Turn the fish once or twice.
- Scrape off the spice mix, wipe and slice thinly on the bias.
Serve
Classically with mustard-dill sauce (mustard, sugar, vinegar, oil and dill), boiled potatoes or on crispbread. Gravad rainbow trout keeps about a week in the fridge wrapped.
