Prep the radicchio
2 long radicchio
Cut each radicchio in half lengthwise, keeping the core intact so the leaves stay together.
Blanch to remove bitterness
Bring a pot of water to a boil. Add ¼ cup apple cider vinegar.
¼ cup apple cider vinegar
Blanch the radicchio halves for 1 minute, then remove and pat completely dry.
Pan-fry
1.5 tablespoon olive oil
Heat 1.5 tablespoons olive oil in a large skillet over medium-high heat.
Cook the radicchio cut-side down until golden, then flip and cook the other side.
Add balsamic glaze
In a small bowl, mix: 2 tablespoons balsamic vinegar ¼ cup + 2 tablespoon water, 1 tablespoon sugar
2 tablespoon balsamic vinegar, Water, 1 tablespoon brown sugar
Pour into the pan. Cook until the glaze reduces and coats the radicchio, turning halfway. Add more water if there isn't enough liquid or if it reduced too much. There isn't meant to be loads of liquid, just a little bit, reduced. Season with salt and pepper.
Make the bean purée
Salt and pepper, 1 can cannellini beans, drained, 1 tablespoon olive oil, salt and pepper
Blend 1 can cannellini beans, 1 tablespoon olive oil, and salt and pepper until smooth.
Add a splash of warm water if needed for a creamier texture.
Plate
Spread the bean purée on a plate, top with the balsamic radicchio, and finish with walnuts, salt, pepper, and any remaining liquid from the pan.
