Combine half of the blue cheese, the lemon juice, Worcestershire, hot sauce, salt and black pepper in a medium mixing bowl. Using the back of a fork, mash the mixture together to form a thick paste. Drizzle in the olive oil, stirring continuously with the fork until the mixture is creamy. Add the sour cream and buttermilk and mix well. Cover and refrigerate for 1 hour. Adjust seasonings with salt and pepper, if needed.
Cut the lettuce into 4 wedges and place each wedge on a salad plate. Spoon about 1/4 cup of the dressing over each wedge. Crumble remaining cheese over each wedge and arrange 2 slices of bacon around each plate. Place croutons around each salad wedge. Garnish with additional cracked black pepper and fresh chives and serve immediately.
Preheat oven to 350 degrees F. Toss garlic bread with the olive oil in a large bowl. Season lightly with the Essence and spread bread onto a baking sheet. Bake until golden brown and crisped through, 10 to 15 minutes.
Combine all ingredients thoroughly.
