Spot prawns are a B.C. specialty. Commercially the traps are set in the spring but personal fishing is a year round option. Chef/fishing guide/son Mark snowboards on Mount Washington on the same day as he does just that. He rinses them and freezes them in water (along with venison, halibut, veggies from his garden, foraged mushrooms and every kind of salmon).
He brought a kg or so to Salt Spring for our family feast, thawed them simply under cold running water....and then! Melted butter and LOTS of garlic.
