I need to de-fat my broth, fast. "The easiest thing is to put the broth in the fridge overnight, but if you have to de-fat quickly, put it in a narrow container," says Bishop. "The fat will rise more quickly to the top and be easier to skim off. You can try to use a paper towel and float that on the surface, but, honestly, if you give it 10-15 minutes, the grease and fat should rise to top. In a narrow vessel, it happens that much quicker."
