Instructions: Preheat the oven to 400 degrees.

Place the Jerusalem artichokes and potatoes in a mixing bowl and season with the salt, black pepper, and cayenne. Mix in 2 tablespoons of the olive oil and toss to coat. Butter the bottom and sides of a 2-quart baking dish. Put half of the artichoke-potato mixture in the bottom of the pan, then sprinkle with 1/4 cup of the chopped onions, 1 teaspoon of the chopped garlic, and 1/4 cup of the cheese and the flour. Top this with the remaining artichoke-potato mixture. Sprinkle with the remaining 1/4 cup onions, 1 teaspoon garlic, and 1/2 cup cheese. Pour the milk over the mixture. In a bowl, mix together the remaining 2 tablespoons olive oil with the bread crumbs, parsley and season with Emerils Essence. Spread this topping evenly over the mixture. Bake for 1 hour, or until the potatoes are tender.
