Xató (sauce)

Xató is a simple Catalan sauce made with breadcrumbs, garlic, hazelnuts, almonds, vinegar, olive oil, dried nyora peppers, and a bit of salt. It is traditionally prepared in a mortar, but home cooks can easily make it in a blender. Originally, xató comes from the Garraf and Penedès regions, where it is usually prepared for the Carnival and used as an accompaniment to different varieties of filled omelets. Apart from that, the sauce is traditionally used as a dressing for the eponymous xató salad that consists of endive leaves, anchovies, Arbequina olives, salt cod, and tuna.
