Directions

1. Make the croutons: Preheat oven to 450 degrees. Combine butter and olive oil in a large bowl. Add bread cubes, and toss until coated. Sprinkle salt, cayenne pepper, and black pepper; toss until evenly coated. Spread bread in a single layer on an 11-by-17-inch baking sheet. Bake until croutons are golden, about 10 minutes. Set aside until needed.
2. Make the salad: Place garlic, anchovy fillets, and salt in a large wooden salad bowl. Using two dinner forks, mash garlic and anchovies into a paste.
3. Using one fork, whisk in pepper, lemon juice, Worcestershire sauce, Dijon mustard, and egg yolk
4. Using the fork, whisk in the olive oil.
5. Chop romaine leaves into 1- to 1 1/2-inch pieces. Add croutons, romaine, and cheese to the bowl, and toss well. If you wish, grate extra cheese over the top. Serve immediately. To make a version of this dressing that you can store, simply mince garlic and anchovies, and place with remaining ingredients in a jar. Screw the lid on the jar tightly, and shake to combine. Shake the jar before each use. Store, refrigerated, for up to 4 days.
