Cook the Brussels sprouts in boiling water until just tender, about 5 minutes. Drain and set aside.
Combine the heavy cream, salt and pepper in a large skillet over medium heat. Bring to a simmer and cook until cream has reduced to 1/2 cup, about 3-4 minutes. Add sprouts and lemon zest and heat through, about 2 minutes. Taste and add salt or pepper as nedded.
You may prepare the whole recipe ahead of time and simply heat before serving. You can also use for other vegetables such as peas, asparagus, beans. Try orange zest instead, and/or add a teaspoons of poppy or caraway seeds. Enjoy.
