ONION SOUP GRATINéE WITH CIDER

Steps:

• Melt butter in a 5- to 6-quart saucepan on very low heat. Add onions and garlic, dust with salt, stir in apples, cover and cook until onions are very soft, about 30 minutes. Stir in sugar, increase heat to high and cook, stirring frequently, about 15 minutes, until onions start to brown. Stir in cider vinegar, scraping bottom of pan.
• Reduce heat to medium-low. Stir in cider, soy sauce and stock, bring to a simmer, cover and cook gently about 20 minutes. Season with pepper and, if needed, more salt. Meanwhile, pile the cheese on the toast slices, covering the bread completely.
• Heat broiler. Divide soup among 6 to 8 ovenproof ramekins, deep bowls or big mugs with about 12-ounce capacity. Place a slice of toast and cheese on each, place ramekins on a baking sheet and broil just until cheese melts and starts to bubble. Serve at once.

Steps:

• Make the soup: In a large saucepan cook the onions in the butter and oil with sugar, salt and pepper to taste over moderately low heat, covered, stirring occasionally, until soft. Uncover and cook over moderate heat, stirring occasionally, until golden brown. Add the flour and cook, stirring, 2 minutes. Add the stock, wine, cheesecloth bag and salt and pepper to taste and cook, partially covered, skimming occasionally, 30 minutes. Season with minced onion and Cognac.
• Preheat oven to 350 degrees F. Arrange slices of bread on baking sheet, brush both sides with melted butter and bake, turning once, for 15 minutes, or until golden. Rub with garlic.
• Transfer soup to ovenproof bowls and cover with bread slices. Sprinkle with cheeses and drizzle with melted butter. Bake for 15 minutes, or until soup is simmering and cheese has melted. Run under a preheat broiler until cheese is golden.

FRENCH ONION SOUP POTATO GRATIN

Steps:

• For the caramelized onions: In a large saucepan over medium-high heat, melt the butter. Once melted and bubbling, add a large handful of the onions and cook until translucent, 1 to 2 minutes. Repeat until all the onions have been added. Season with a pinch of salt and black pepper. Reduce the heat to low and cook, stirring occasionally, until the onions turn medium brown, about 30 minutes. If the onions start to get too dark, add 1 to 2 tablespoons of beef stock as necessary. Add the sherry to deglaze the pan. Add the mustard and stir to coat. Season with salt and pepper. Remove from the heat and set aside.
• For the potato gratin: Preheat the oven to 400 degrees F.
• Using a mandoline or a sharp knife, cut the potatoes into thin slices. Do your best to keep the potatoes in a stack--this will make it easier to layer them in the pan. Set the potatoes aside.
• Use the reserved butter wrapper to lightly grease the bottom and sides of a large (12-inch) cast-iron skillet. Discard the wrapper.
• Arrange a thin shingled layer of potatoes in concentric circles around the skillet. Season the potatoes with salt and pepper, then arrange an even layer of caramelized onions on top of the potatoes. Season with salt and pepper.
• In a medium bowl, combine the Gruyere and mozzarella and reserve half for later use. Sprinkle on a layer of the remaining cheese mixture over the onions. Repeat the layers until all the ingredients (not including the reserved cheese) have been used. Press down firmly on the layers to flatten.
• In a large bowl or measuring cup, combine the heavy cream and beef stock and pour over the gratin. Cover the skillet with foil and place on a sheet pan. Bake the potatoes, covered, until the top and edges have begun to brown and the potatoes are tender, 1 hour 15 to 1 hour 30 minutes. You can test by inserting a knife into the potatoes; if it goes in and comes out without resistance, then the potatoes are done.
• Remove the skillet from the oven, remove the foil and turn the broiler on high. Combine the croutons and French fried onions. Cover the gratin with a layer of the crouton mixture followed by the remaining cheese. Broil until golden brown and bubbly, 5 to 8 minutes. Serve and enjoy!
