Make a large batch of this dressing to keep in the fridge, as it’s a creamy, tangy dream that is perfect for dressing bitter greens, slaws, and hot potatoes.
2 tsp Dijon mustard
2 Tbsp finely chopped capers
1 Tbsp caper liquor (the liquid from the caper jar), or 1 Tbsp apple cider vinegar
3 Tbsp extra virgin olive oil
1 witloof and/or radicchio
1 bag bitter greens, such as watercress, rocket, or baby kale.
In a small bowl, combine the mustard, capers, vinegar, and olive oil. Season with salt and pepper to taste. If a little thick, loosen with 1-2 tablespoons water.
Separate the witloof leaves and place them into a large serving bowl, along with the watercress. Add enough dressing to coat and serve immediately.
