Anchovies with lamb might sound like an unusual pairing but please bear with us, this dish is a classic that packs a serious flavour punch.

Anchovies are a rich source of umami. The word umami derives from a Japanese word meaning “pleasant savoury taste” - it describes foods that are fundamentally savory in nature.

Umami comes from three compounds that are naturally found in plants and meat: glutamate, inosinate, and guanylate. The first, glutamate, is an amino acid found in vegetables and meat. Iosinate is primarily found in meat, and guanylate levels are the highest in plants.

Other foods rich in umami are parmesan cheese, certain mushrooms, cooked tomatoes, soy sauce, some seaweeds and other dried fish that have been used for centuries by cultures all over the planet to bring this intriguing flavour that we crave. 

The ancient Greeks and Romans produced a prized sauce called garum which was made from ingredients including the fermented salted intestines of anchovies which was very rich in glutamate and hence umami.

Here in the UK we have our own version of this in most supermarkets called Worcestershire sauce. This staple in our cupboards is a dark brown condiment made from fermented anchovies, vinegar, sugar, and spices. Worcestershire sauce likely evolved from a Malaysian condiment similar to Indonesian kecap manis, a sweet, thick soy sauce.

So this is why we love anchovies in this recipe, but how should we source them?

Anchovies are a resilient species and as such can sustain relatively high levels of fishing pressure, however there are certain marine environments that are more sustainable than others to source from.

The Marine Conservation Society says: 

The sustainability of European anchovies varies. Check the label for where they are caught, Bay of Biscay anchovies are the Best Choice! European anchovies caught in Atlantic Iberian waters or Northwest Africa (such as Morocco or Mauritania) are OK, but fishing here is not as well controlled.

Unprocessed anchovies are a relatively mild tasting fish but the anchovies you're probably most familiar with, the ones that come in jars or cans and turn up in pizzas, pastas, sandwiches, have been filleted, salt-cured, and stored in olive oil. It's that curing process that produces the intensely salty flavor and pungent, fishy odor commonly associated with anchovies. It's also what's responsible for breaking down the myosin in the fish—one of the muscle proteins that hold its flesh together—making it exceedingly easy to mash up and dissolve. These are the ones we want for that rich umami decadence that will take this lamb dish to a new level of lip smacking deliciousness.
