I photographed this recipe from one of my oldest and most favorite cookbooks, THE OLD-FASHIONED COOKBOOK by Jan McBride Carlton. It was published in 1975 and I grab it first when looking for a recipe.
When I prepare this potato salad, I mix the hot dressing over the potatoes that have been cooled slightly in cold water but are still hot. I leave the red-skin peeling on and cut into cubes before cooking. The dressing makes this dish. Try it and let me know if you like it. I always get compliments when I bring it to a pot luck. People love it and are always surprised that it is somewhat sweet. Anyway, try it with the sugar the first time around. It's a fabulous recipe for the 4th of July or for Father's Day this weekend. xo
Here is a used book search with some very inexpensive prices if you want to buy a copy. The American First edition is earlier (1975) than the English one published in 1984.
