Make this recipe a recipe that people in that category can eat. categories: ['vegetarian'], recipe: in a food processor or blender, mix mustard, salt, egg, and vinegar. add oil very slowly, beating constantly. add lemon juice. pulse in minced garlic, oregano, worcestershire sauce, and pepper. refrigerate mixture. note: the risk of illness is very low with raw eggs, but to be sure, use a pasteurized egg.

Target recipe: in a blender or food processor, whirl all the ingredients except the buttermilk for one minute. with the blender running, slowly pour in the buttermilk and blend until thick and creamy (turn off the blender as soon as the dressing thickens or it may curdle). chill at least 1 hour so the flavours meld. refrigerate, tightly covered. this makes nearly 2 cups of dressing and stays fresh for 3-4 days. if the dressing separates, just give it a whizz in the blender again.
