Plump fillets smoked for us at a smokehouse on the Severn, they are delivered in packs of two. Traditionally served with horseradish sauce, we prefer the horseradish mixed with mayonnaise or double cream so it's not too strong, and the smoked mackerel always makes a quick and easy meal with brown bread and butter and a wedge of lemon. So easy to make a great pate in the the food processor, with some cream or fromage frais and a dash of chilli and lemon juice.
