I'm really excited to make the soup. However, I am having a problem making the beta-carotene butter. It seems as though the emulsified carrot juice and butter is not separating in my refrigerator. Therefore, I am not having any congealed butterfat to scoop out. The mixture remains in emulsion. Does anyone have any suggestions? I am following the recipe precisely as described in MCAH (carrot juice and butter).
