Instructions

  1. Step 1: Heat 3 tbsp extra virgin olive oil in a large skillet over medium-high heat until shimmering. Add 2 heads of radicchio quartered and sauté for 3-4 minutes per side until the edges are slightly charred and the leaves soften but maintain structure.
  2. Step 2: While the radicchio cooks, whisk together 3 tbsp bitter orange juice, 1 tbsp balsamic vinegar, 1 tsp Dijon mustard, 1 tsp honey, and a pinch of 1 tsp salt and 1/2 tsp black pepper until emulsified.
  3. Step 3: Remove the radicchio from heat and immediately drizzle with the bitter orange vinaigrette to coat. Serve warm to enjoy the contrast of bitter and sweet flavors.
