Toss chicken in flour. Dip tenders into buttermilk wash, allowing excess to drip off. Place tenders in pecan breading, scooping mixture on top and pressing coating lightly on tenders. Deep fry until golden.
For sauce, mix dry mustard with cider vinegar. Let rest, covered, at room temperature overnight.
Combine mustard mixture with 2 beaten eggs and sugar. Using a double boiler, cook until sauce thickens. Cool before serving with chicken tenders.
