Step 1

Preheat oven to 350 degrees F (175 degrees C).

Step 2

Trim off the top of the head of garlic to expose cloves. Drizzle with olive oil. Sprinkle salt and black pepper on top. Wrap in aluminum foil.

Step 3

Bake in the preheated oven until garlic feels soft when lightly pressed, about 1 hour. Unwrap and cool, 5 to 10 minutes. Refrigerate until chilled, 30 minutes to 1 hour.

Step 4

Pull out individual garlic cloves with a sharp knife; place in a small bowl. Mash with a fork until creamy. Add mayonnaise, lemon juice, Worcestershire sauce, and cayenne; mix well until blended.

Step 5

Refrigerate until flavors combine, at least 1 hour.
