Lemon-Anchovy Vinaigrette

Ingredients
Method
Cut all peel and white pith from lemons; discard. Working over a medium bowl, cut lemons along sides of membranes to release segments into bowl. Squeeze in juice from membranes and discard membranes.
Mix in anchovies, oil, and red pepper flakes, breaking up lemon segments against the side of the bowl with a spoon; season with salt and pepper.
DO AHEAD: Dressing can be made 4 days ahead. Transfer to a jar; cover and chill.
