Apple Sauce Salad Dressing

Cook an apple sauce with very little water and no sugar. To a cup of hot apple sauce add from one-fourth to one-half cup of butter. Whip thoroughly. Unless apples are very sour, add the juice of half a lemon, and a little sugar if you like. Do not salt it. Whipped apple sauce will also emulsify and retain oil, but the butter dressing is the finer flavor.
