This recipe is best made with freshly ground clams, although it would still be good with finely chopped clams. Canned would be OK, and better to make it with canned than not at all, but please, please, please make this at least once with fresh clams. You will not be sorry. Use cake flour if you can get it; it will make a lighter, fluffier cake. All-purpose is fine if you can't find cake flour. Use a "regular" beer, not a fancy one. Think Budweiser. For the remoulade, I used a recipe I developed with Elise from Simply Recipes. Be sure to keep your oil as close to 350°F as you can. The cakes will come out greasy if your oil gets too cool. Fry in batches to prevent this.
If you can't eat all the cakes in one sitting, leave the oil in the fryer overnight; it'll be fine. Then reheat and refry the leftover cakes for 2 to 3 minutes, turning once. If you want a more traditional New England Fried Clam recipe, I got one.
