This vintage salad dressing recipe is a creamy, tangy concoction hailing from the early to mid-20th century, likely passed through generations via handwritten cookbooks. Often used in Midwestern American cuisine, this style of dressing was popular before commercial mayonnaise became widespread. It's a cooked custard-like dressing with a sweet and sour profile, ideal for potato salads, coleslaws, or as a spread in sandwiches. Its simple ingredients reflect a time of resourceful home cooking where taste was built with pantry staples like vinegar, egg yolks, and butter. Today, itβs cherished for its nostalgic charm and versatile flavor.
