Preparation

Put potatoes in a pot with cold water to cover.
Bring to a boil, reduce heat and boil gently 10 to 15 minutes until just tender when pierced.
Drain.
Meanwhile mix vinegar, sugar, mustard, salt, pepper and garlic in a large bowl.
Add sliced onion.
When potatoes are cool enough to handle, cut in 1/4-inch thick slices.
Add to dressing and turn gently with a rubber spatula to mix and coat.
Let stand at least 15 minutes for potatoes to absorb some dressing.
