Unlike hard shell clams (known here as quahogs, cherry stones, or little necks, depending on their size), steamers have rather thin, brittle shells, so you have to be gentle with them. The two sides of the shell don’t close all the way. Instead, protruding from the shell is a long foot, or siphon. It’s what the soft shell clam uses to filter the sea water and eat. While hard shell clams stay close to the surface of the sea floor, steamer clams bury themselves more deeply and extend their long siphons to the seafloor surface.
Happy as Steamed Clams
When you buy steamer clams, their siphons are mostly tucked away. But as soon as you soak them in (salted) water, the siphons start to come out, and out, and out. When we made these steamed clams the other day I think we measured one that was a good 4 inches long! (Could it be where the phrase, “happy as a clam” comes from?) Anyway, soaking the steamers is a great way to freak out kids, though hopefully not so much as to dissuade them from eating steamed clams. Fortunately, my gang loves seafood. I just had to tell them these steamed clams were like mussels, but with convenient handles for dipping into melted butter. After a while, you’ll notice that each clam has a foot that will start to extend out of the shell. This is normal. The clams are usually buried in the sand with only the foot extending up to the surface of the water. The steamer clams will discharge any sand or dirt while they are sitting in the water, so the water may become rather murky. You can change the water if you want. If you don’t have time to let the clams soak for hours, just put several of them at a time in a large bowl, cover with salt water, and gently swirl the water around with your fingers for half a minute. If the clams release sand or grit, dump out the water and rinse the clams out in the same manner again, until no more sand is released. (They may still release some sand and grit while cooking, but you will dip them in the clam broth before dipping them in butter when you eat them, helping to rinse away any remaining grit.) The clam shells are on the thin side and can easily break, so be gentle as you put the steamers in the pot. You may notice some of the clams “spitting” water at you as you handle them. This is normal, don’t worry about it. If any of the clams seem dead, are stinky, or whose siphons don’t retract a bit when you touch them, toss them out. Cover the pot. Bring the water to a boil. Let the clams cook in the steam from the boiling water for about 5-10 minutes, until the steamer clam shells are wide open, then remove the pot from the heat. Any steamers that didn’t open should be discarded. (The pot might foam up and boil over while cooking, so keep an eye on it while cooking.) Let the clams cool for a couple minutes. Grip the siphon with your fingers, swirl the clam around in the hot broth (it will help to warm up the clams and to dislodge any remaining grit or sand). Dip the clam into melted butter and eat! Note, the siphon end of the clam may be a bit tough and rubbery. You can eat it or not. In any case, it makes a great handle for dipping.
