A delicious sustainably sourced mackerel salad.

Mackerel: Remove the skin of the mackerel and flake into chunks.
Potatoes: Cook in plenty of boiling salted water until cooked and allow to cool in the cooking liquid (do not refresh under cold running water).
Horseradish Mayo: 10g Coleman’s creamed horseradish, 25g mayonnaise – whisk together


Mix the warm potatoes with the horseradish mayonnaise
Season with Maldon and freshly ground black pepper
Toss together the watercress and smoked mackerel with the rapeseed oil and lemon juice, season with freshly ground black pepper
Place the WARM potato salad roughly on the base of the plate
Top with the watercress and smoked fish

The potatoes need to be warm as this takes the chill off everything.
