Clean and cut your carrots into 1 1/2" pieces, or as close to that as you can get them. They won't all be exactly the same. Melt the butter in an 8" skillet and add the carrots and Hendrickson's dressing, turn heat up to med high and get the dressing boiling, cover and cook for 3-5 minutes. Uncover and turn the heat down to med and continue to simmer until the dressing has evaporated and is syrupy and sticky. Stir to coat the carrots well and serve.
