How to Make It
Cook bacon in a large heavy skillet (preferably cast iron) over medium-high, stirring often, until it begins to brown and crisp, about 6 minutes.
Add radishes; stir to coat in bacon drippings. Stir in sugar, salt, and pepper. Cook, stirring often, until bacon is crisp and radishes are tender-crisp with a few browned, caramelized edges, about 10 minutes. Add the radish greens; stir until slightly wilted.
Sprinkle mixture with thyme, and drizzle with lemon juice. Serve warm.
