This is the best burger recipe for several reasons. One, this recipe for beef burgers is made with grass-fed beef. That makes these burgers healthier for the environment and your family since grass-fed beef is higher in cla, a heart-healthy fatty acid. Look for grass-fed beef at trader joes, whole foods, or other natural food stores. The second reason this is the best burger recipe is that these beef burgers are incredibly juicy and tasty, thanks to a secret ingredient: a touch of cream and a light brush of butter on the outside. Note: you must cook these burgers on lower heat or they will burn.
