Prepare the crabs by removing the eyes, dead-men (spongy grey gills), and sand sack. Heat 3 tablespoons of the butter and the oil in a heavy skillet until hot and sizzling. Add the crabs. Saute a few minutes on each side. Remove to a warm plate.
Meanwhile, brown the pecans in 1-2 tablespoons butter. Pour over the crabs and serve. From Nathalie Dupree's New Southern Cooking
