This is my all time favorite potato salad recipe and potato side dish. My sister started making this about 30 years ago. She hasn’t been able to find the recipe, but did recall the ingredients. Instead of using all-purpose flour, as in a traditional German hot potato salad recipe, I used potato starch. I can’t remember the last time I made this and have lost the recipe, as well. What makes this recipe stand apart from other German Hot Potato Salad recipes is that the apple cider vinegar, combined with celery seed and a little bacon grease. Our entire family loves this recipe so much, we must have had it for about 20 straight years with our Christmas ham (with very few exceptions). It’s hard to believe Christmas is just 3 months away! I had to wing it on the quantities, but it tastes just like I remember – oh so good! Of course, I was always known for increasing the bacon and almost doubling the sauce. What are holidays for, right? This time I made it as the old recipe called for, as I just had 4 slices of bacon. That is actually what precipitated me making this dish. I did increase the sauce, however. Enjoy!
