Rinse and scrub your taters.
Cut them into a little larger than bite-sized cubes. I go lengthwise first.
Then into fourths or so.
Cover potatoes with cold, salted water. Bring to a boil. Once boiling, cook for about 10 mins. Start checking for doneness around the 7 minute mark. Drain and run under cold water to stop cooking process.
While potatoes are boiling, whisk together honey, mustards, lemon juice, and vinegar.
SLOWLY whisk in the olive oil. Season with salt and pepper.
Place your potitties in a large enough bowl for mixing. Add radishes, celery, scallion, and capers.
Toss ingredients together, adding your hunty-mustard vinaigrette a little at a time, until it's happily dressed.
Taste again and adjust seasoning if necessary. I usually salt again here, after all ingredients have been combined. Personal preference.
Refrigerate until chilled, at least an hour. Serve cold.
Pull down your pants and ENJOY!
