In a 2-quart jar, place beet slices; top with turnip slices. Add peppercorns, red pepper, and bay leaf.
In a medium saucepan, bring vinegar, ¼ cup water, and sugar to a boil over medium-high heat. Remove from heat, and stir until sugar is dissolved. Pour over turnips. Cover and let cool to room temperature. Refrigerate overnight or up to 2 weeks.
