I often grill in Winter, with my own pesto, Parmesan cheese, bread crumbs on the top , one day I cook pasta when I could not find fresh and good small clams, it was fantastic now all my family prefer razor clam pasta than bongole,its sweet taste and slightly meaty than usual clam with plenty of garlic, chilli,and very good olive oil, with dry white wine chopped parsley! DO try!
BUT be careful not over cook the razor clams, if you do it, will be robbery as any seafood, over cooked razor clams are too hard and chewy. Needs 1 minutes only (remember, under cook is much better than over coo in this case) to cook.
I love ceviche as a raw fish loving Korean, ceviche is most refreshing fish dish for me. As long as fish or scallops, razor clams are fresh, simply the best for me. As for fish, wild sea bass, skate are the best.
I made razor clam ceviche for our special meal first course. it was superb ,so tasty , I love the texture better than scallops for me. Serve in its own shell, looks so pretty as well.
Wash the razor clam and plunge into boiling water for 2 seconds , if you do not like the idea of cleaning live ones, the flesh pop out and clean, chop, leave aside, 1tbsp lime or lemon juice, 1 tsp lime or lemon zest 1 red chilli chopped, red onion chopped, and mix all in a bowl, season with salt, leave in the fridge 10-15 minutes and serve with a good sourdough bread.
Do not marinate more than 15 minutes, Delicious!!!
