Aoc'S Long Cooked Cavolo Nero (Tuscan Kale) - cooking recipe

Ingredients

4 bunches cavolo nero or 4 bunches tuscan kale, stemmed and cleaned
1/4 cup olive oil
1/2 white onion, thinly sliced lengthwise
1/2 sprig rosemary
1 dried arbol chile (this is a red chile, use cayenne pepper if you can't find the chile)
2 garlic cloves, thinly sliced
1/2 teaspoon salt, divided, more as needed
2 tablespoons chicken broth (optional) or 2 tablespoons water (optional)

Preparation

Blanch the cavolo nero in a large pot of salted, boiling water just until softened slightly, 2 to 3 minutes. Drain the cavolo nero and immediately place it in a bowl of ice water to cool. Drain again and set aside.
In a large, heavy-bottom saucepan heated over medium-high heat, add the olive oil, onions, rosemary and chile de arbol. Gently saute for 2 minutes, then add the garlic and season with one-fourth teaspoon salt. Continue to cook until the onions are transparent and just beginning to color, an additional 8 to 10 minutes.
Stir the cavolo nero into the pan and cook over medium heat, stirring often, for 30 to 40 minutes. As it cooks, the cavolo nero will turn a deep dark green, almost black color, and the texture will go from soft to almost a little crisp from caramelizing on the bottom of the pan. This is good and will enhance the flavor. If the cavolo nero becomes too dry, add a little stock or water to moisten the bottom of the pan. Season with the remaining one-fourth teaspoon salt and remove from heat. Serve immediately.
