Heat 2 tablespoons of canola oil in a large skillet over medium heat. Add the onion, bell pepper, celery, garlic, and cook until softened, about 5 minutes. Transfer to a large mixing bowl and let cool to room temperature.

When cool, stir in the crabmeat and 1 1/2 cups of the cracker crumbs. Whisk the mayonnaise, eggs, heavy cream, mustard, cayenne and Worcestershire sauce together in a separate bowl. Using a spatula, fold into the crabmeat mixture. Chill for one day.

Heat 3 to 4 tablespoons of canola oil in a large skillet over medium heat.

Transfer to a plate lined with paper towels. Serve with rémoulade sauce, or a sauce of your choice.
