FRENCH ONION SOUP

Steps:

• Trim the ends off each onion then halve lengthwise. Remove peel and finely slice into half-moon shapes. Set electric skillet to 300 degrees and add butter. Once butter has melted add a layer of onions and sprinkle with a little salt. Repeat layering onions and salt until all onions are in the skillet. Do not try stirring until onions have sweated down for 15 to 20 minutes. After that, stir occasionally until onions are dark mahogany and reduced to approximately 2 cups. This should take 45 minutes to 1 hour. Do not worry about burning.
• Add enough wine to cover the onions and turn heat to high, reducing the wine to a syrup consistency. Add consomme, chicken broth, apple cider and bouquet garni. Reduce heat and simmer 15 to 20 minutes.
• Place oven rack in top 1/3 of oven and heat broiler.
• Cut country bread in rounds large enough to fit mouth of oven safe soup crocks. Place the slices on a baking sheet and place under broiler for 1 minute.
• Season soup mixture with salt, pepper and cognac. Remove bouquet garni and ladle soup into crocks leaving one inch to the lip. Place bread round, toasted side down, on top of soup and top with grated cheese. Broil until cheese is bubbly and golden, 1 to 2 minutes.

TEST KITCHEN'S FAVORITE TOMATO SOUP

Steps:

• Heat oil and butter in a large saucepan over medium-high. When butter melts, add onion, garlic, and 2 teaspoons salt. Cook, stirring often, until soft and golden, 6 to 8 minutes. Stir in flour; cook 1 minute. Add tomatoes and juice, broth, and basil sprigs. Bring to a boil, then cover, reduce heat to low, and simmer until tomatoes are very soft and breaking down, about 20 minutes. Discard basil sprigs and let cool slightly.

OUR FAVORITE FRENCH ONION SOUP

Steps:

• In a large Dutch oven or other large pot, melt 3 tablespoons butter over medium heat. Add the oil and onions; cook onions are until softened, stirring occasionally, about 15 minutes. Add the salt, pepper, and sugar; continue to cook, stirring occasionally, until onions are deep golden brown and caramelized, reducing heat slightly if onions seem to be browning too quickly, 35 to 45 minutes more.
• Add wine and raise heat to high. Cook until almost all liquid has evaporated, 8 to 10 minutes.
• Tie thyme and bay leaves into a bundle with twine. Add broth and herb bundle to pot with onions. Bring to a boil, reduce to a simmer, and cook, uncovered, until broth is thickened and flavorful, 20 to 30 minutes. Remove from heat and whisk in remaining 2 tablespoons butter. Taste and adjust seasoning.
• Heat the broiler. Cut two 1/2-inch baguette slices for every serving of soup. Place baguette slices on a rimmed baking sheet and toast in oven until crisp and dry but not browned, about 1 minute per side. Rub one side of each toast with the garlic clove and set aside.
• Place ramekins or ovensafe bowls on a rimmed baking sheet, add 1/2 teaspoon of sherry to the bottom of each, and ladle soup on top. Top each serving of soup with two garlic-rubbed toasts. Divide cheese among the servings, covering the bread and some of the soup. Carefully transfer baking sheet to oven and broil until cheese is melted and bubbling, 4 to 8 minutes. (Alternatively, if using regular soup bowls: Top each garlic-rubbed toast with some cheese and return to broiler to melt, about 2 minutes more. Divide sherry and soup among bowls, sprinkle with remaining cheese, and top each serving with two cheese toasts.)
