Preheat the oven to 400 degrees F.
Butter 6 individual round au gratin ramekins and place on a baking sheet.
In a saute pan, over medium heat, add the oil. When the oil is hot, add the onions, bell peppers, and celery. Season with salt and pepper. Saute for 1 minute. Add the garlic and saffron. Continue to saute for 1 minute. Add the rice and stock. Cover and cook for 20 minutes, or until the water is completely absorbed. Remove from the heat and set aside. This makes about 3 cups of cooked rice.
In a small saute pan, over medium heat, render the bacon until crispy, about 6 to 8 minutes. Remove and drain on paper towels. Set aside.
In a food processor, fitted with a metal blade, combine the egg, garlic, ketchup, 2 tablespoons of the parsley, dry mustard, paprika, and vinegar. Process until smooth. Season with hot pepper sauce, salt and pepper. With the machine running and in a steady stream, add the oil, 1-tablespoon at a time. Season with salt and pepper.
To assemble, spoon 1/2 cup of the rice filling evenly over the ramekins. Season the crabmeat with salt and pepper. Place a sixth of the crabmeat over each ramekin of rice filling. Spread the Remnick dressing evenly over each ramekin of crabmeat. Place in the oven and cook for 6 to 8 minutes or until the top is golden and bubbly. Remove from the oven and garnish with the crispy bacon, remaining parsley, and lemon twists.
