Pickled Turmeric Eggs

In a small saucepan bring the vinegar, water, sugar, salt, and turmeric to a simmer. Stir until the sugar dissolves. Place the onion, peppercorns, and eggs in a glass quart jar. Pour the vinegar mixture over the eggs, secure the lid, gently rotate to move the shallots around, and refrigerate for up to ten days - two weeks.
