How to Make Green Beans and Carrots using the Buerre Fondue Technique

STEP ONE: Blanch the Vegetables
Bring a large pot of salted water to a boil. Add the carrots and cook for 4-5 minutes until just tender. Add the green beans and cook for an additional 3-4 minutes.
Drain and immediately transfer to an ice bath to stop the cooking. Once cooled, drain again and set aside.

STEP TWO: Prepare the Beurre Fondue
In a wide skillet, add 2 tablespoons of cold water over low heat. Once the water is warm, begin whisking in 6 tablespoons of cold, cubed butter, one piece at a time.
Let each cube melt and fully emulsify before adding the next. This process should take about 4 to 6 minutes. Keep the heat low to avoid breaking the sauce.

STEP THREE: Add Thyme and Vegetables
Add the thyme sprigs to the butter sauce and let them steep for 1-2 minutes, then add the carrots and green beans, tossing gently with salt and pepper as they warm through for 2-3 minutes.
Push the vegetables to one side and whisk in the remaining butter until it melts and the sauce turns glossy.

STEP FOUR: Finish with Lemon Zest
Toss to coat everything evenly. Remove the thyme sprigs if desired, and garnish with lemon zest just before serving.
