1. Place potatoes into a large pot and cover with salted water; bring to a boil. Reduce heat to medium-low and simmer until just tender, about 15 minutes; drain. 2. Put potatoes into a large bowl; add onion and stir. 3. Mix sugar, mustard, and salt together in a bowl. Stir just enough vinegar into the sugar mixture to form a paste; season with black pepper. 4. Whisk remaining vinegar and vegetable oil together in a separate bowl until smooth; stream into bowl with the paste, whisking continually to incorporate. Pour the dressing over the potato and onion mixture. 5. Cover the bowl with plastic wrap and let salad cool slightly, 5 to 10 minutes. ---------------------------------------------------------------------------
