Every Easter my Mom would make this potato salad. This is not exactly hers but my version. Don't wait for Easter make it for your next picnic! Do use new potatoes if you like them firm but I myself like my potatoes soft so I find myself using russets, and if you don't want a precise cut salad with firm potatoes use russet. I find myself rough cutting the russets potatoes because they do fall apart and add to the creaminess of the dressing. FYI-You can toss the cubed, cooked, still warm, potatoes with the vinegar or beet juice and let set till cool even up to over night. Then add remaining ingredients.
