A Christmas tradition around our house, it goes quickly and I end up making it several times over the season, especially good toasted regular or under the broiler with a little cheddar sprinkled over.
Chorizo and fish work so well together. Make sure you use the best-quality chorizo you can find; it comes in spicy and sweet varieties, but I tend to always go for the spicy one! The pangrattato sprinkled on top adds a lovely crunchiness to the soup and is well worth the little bit of extra effort.
Quick-pickled cukes give these burgers tart crunch. Panko and egg white hold the patties together. Use cilantro leaves on the burgers as you would lettuce for herby freshness.
