Whole roasted fish

1 To make the cure, mix the salt, sugar, citrus zest and dill.
2 Toast the spices in a pan until fragrant. Blend the spices, then mix with the cure.
3 Pack the cure (and beetroot, if using) evenly over the trout fillets and cover with clingwrap. Chill for 2 days, draining the excess liquid at the end of each day, ensuring the crust remains intact.
4 Remove the cure and pat dry the fish using kitchen paper. Store in an airtight container.
5 Before serving, thinly slice using a sharp knife. Serve with fresh lemon, chopped dill and horseradish cream. The gravadlax will keep in the fridge for 2–3 days.
Cook's note: (ask your fishmonger to fillet and pin-bone the trout)
