Ingredients

FOR THE BROWN BUTTER MAYONNAISE:

  • 12 tablespoons unsalted butter
  • 1 large egg yolk at room temperature
  • 2 teaspoons freshly squeezed lemon juice
  • 1 teaspoon cold water
  • ¼ teaspoon kosher salt plus more to taste

FOR THE BLT:

  • 2 slices bread gluten free or regular
  • 2 slices pork or turkey bacon halved
  • 2-3 thick slices heirloom tomato
  • 2 leaves Little Gem or romaine lettuce

Instructions

  1.  In a small skillet or saucepan over medium heat, melt the butter completely; cook until it turns brown and smells nutty, about 4 to 6 minutes. Be sure to stir frequently, scraping up any bits from the bottom so they don't burn. Take the pan off the heat and transfer the brown butter to a glass measuring cup with a spout. Let cool to just above room temperature. Combine egg yolk, lemon juice, cold water, and salt in a medium mixing bowl. Whisk until well integrated and bright yellow, about 30 seconds. Whisking constantly, add about half of the brown butter to the yolk mixture, a few drops at a time. Do not add the brown butter too rapidly; or an emulsion will not form.

    Gradually add remaining brown butter in a very slow, thin stream, whisking constantly, until mayonnaise is thick and spreadable. The process should take around 6-8 minutes (this step can also be done in a food processor. Season to taste.

  2. Toast bread and spread one slice (or both slices) evenly with brown butter mayonnaise.
  3. Layer bacon, tomato and lettuce over a slice of bread and top with the other slice.

Recipe Notes

The mayo also makes for an amazing addition to any salad dressing
