Eight minutes, no heat, and it is the best thing you can do with a tin of mackerel and a packet of oatcakes.
Drain the oil but not completely. A spoonful of it back in the bowl carries flavour that plain mayonnaise does not have. Pour the rest away.
- Mackerel into a bowl. Mash with a fork, but stop early: you want flakes and some texture, not paste. About fifteen seconds of work.
- Mayonnaise, lemon juice and paprika folded through. Fold rather than beat.
- Pepper, then taste. It will probably want more lemon than you expect, because the oil and the mayonnaise are both rich and the acid is the only thing cutting them.
Better after ten minutes standing, if you have them.
Oatcakes rather than crackers, because they are sturdier and the oats stand up to something this rich. Cream crackers work and go soft faster once loaded.
Serves 2 generously as lunch.
