Mackerel in Mustard Sauce

Conservas Santos is a Portuguese conservas producer rooted in the traditions of the Iberian canning industry. This mackerel tin steps outside the standard oil-and-salt format into something more complex and sauce-based — Atlantic mackerel in a mustard sauce made with vinegar, vegetables, and spices, a preparation with deep roots in the French and northern European conservas tradition.

Mackerel is a rich, boldly flavoured fish, and mustard is one of its most natural companions: the sharp acidity of the vinegar-based sauce cutting through the fat of the fish, the mustard adding pungency and depth, and the vegetables and spices rounding everything out into a sauce that is tangy, savoury, and genuinely satisfying.
