  • 1 to 2 romaine or iceberg lettuce leaves
  • 1 vine-ripened tomato, sliced 1/4 inch thick
  • 3 to 4 basil leaves
  • 2 slices thickly cut bacon, cooked

    • 1 teaspoon Dijon mustard
    • 1 teaspoon fresh lemon juice
    • Coarse salt
    • White pepper
    • 1 cup grapeseed, sunflower, or safflower oil

Directions

  1. Spread one side of one slice of toast with butter.

  3. Spread remaining slice of toast with mayonnaise; place mayonnaise side down to form a sandwich and cut on the diagonal. Serve immediately.
  4. For the Mayonnaise
    1. By hand: Place egg yolk, mustard, lemon juice, 1/4 teaspoon salt, and a pinch of pepper in a bowl and whisk together until mixture is smooth and thoroughly combined. Add the oil: Start with one drop at a time and whisk constantly until mixture begins to thicken; add remaining teaspoon lemon juice, then pour in oil in a very slow, steady stream and continue whisking until oil is incorporated and sauce is thick and emulsified. Use immediately or refrigerate in an airtight container for up to 1 week.
    2. Blender method: Combine egg yolk, mustard, lemon juice, 1/4 teaspoon salt, and a pinch of pepper in the jar of a blender or in a large glass measuring cup, if using a hand blender. Blend until smooth and thoroughly combined. Add oil, starting with one drop at a time, and blend constantly until mixture begins to thicken. Add remaining lemon juice while continuing to blend, and pour remaining oil in a slow and steady stream until oil is incorporated and mixture is thick and emulsified.
