How to turn shellfish shells into stock – recipe

Shellfish are an expensive delicacy, so are well worth using in their entirety. Fortunately, even once it’s been picked of all accessible meat, the rest of the crustacean is useful from shell to claw. Even the most experienced shellfish eater will leave some meaty morsels in the nooks and crannies of the carapace, while the heads are full of flavourful juices that can be sucked out or combined with a holy trinity of stock vegetables and aromatics to make an exquisite stock for bisques, broths, risottos or paellas. Collect picked shells in the freezer until you have enough to make today’s small-batch recipe, or bulk it out with other fishy remnants if necessary.

A rich, nourishing stock is a great way to ensure you get the most bang for your buck when you treat yourself to a shellfish dinner. Homemade shellfish stock will up your home cooking game, helping you make the most flavourful, restaurant-quality paellas, risottos, gumbos and curries at home.

If your oven is already in use, instead of sauteing the shellfish shells, roast them at a high heat – 240C (220Cファン)/475F /ガス 9 約 10 分, which has the added bonus of ensuring a a more even caramelisation (しかしながら, avoid roasting shellfish with other foods that might absorb its odour).

Whenever we cook shellfish at home, I semi-automatically get a pot of stock on the go after the meal, and if you go down that route, add any appropriate leftover vegetables from the meal to the stock pot, あまりにも.
