My aunt Madge used to make this unique dish for family reunions. This version takes her classic recipe and updates it slightly with the addition of mustard and dill.

Cut potatoes into bite-sized chunks (do not peel). Place in pot and cover with water, adding a liberal amount of salt. Boil until soft, 15-20 minutes. Drain well and dry inside of pot. Dice bacon and fry in same pot until done but not crisp; scoop with slotted spoon onto paper towel-lined plate, retaining grease in pot. Dice onion and celery and saute in bacon grease until soft, 7-8 minutes; scoop with slotted spoon onto bacon plate. Whisk in vinegar (scraping any brown bits from bottom of pan), then flour, sugar, mustard, dill, salt, and pepper. Add potatoes, bacon, and onion/celery, and stir well over low heat, allowing dressing to absorb. Serve warm or room temperature.
