Slice calamari into 1/4 inch rings. toss with salt, pepper, and corn meal. In a large pot, melt the butter over high heat. As it begins to sizzle add the calamari and sauté for about 2 minutes, until the outside turns gold. Remove from pan and set aside. To the hot pan, add the celery and onion. Cook until softened and slightly translucent over medium heat. Add the garlic and tomato paste. Stir until the tomato paste takes on a deep red color, almost brown.
Deglaze the pan with wine and add the crushed tomatoes and anchovy paste. stir in 1 tbsp hot chopped peppers and 1 tsp hot red pepper flakes.
Simmer while adding the stock. Stir in herbs, then cover and let cook for 15 minutes over medium heat. Meanwhile boil water for pasta. When adding pasta to the salted water add the bay scallops, spinach and pre-cooked calamari to the sea stew. Stir in lemon zest and 2 tbsp lemon juice. (let this cook about 5 minutes over low heat)
After draining, serve heaping scoops of stew over the pasta. Garnish with herbs and a lemon wedge.
