Steak Weight Steak Weight - Great for pressing bacon flat in the pan when wanting to get out the most grease to use for infusing spirits. Made of cast iron a wooden handle. 5 3/4" x 9 1/2". Fat Washing Fat washing is when you infuse a fat such as bacon grease or melted "real" butter with a spirit. For example, if you were making a bacon infused Bourbon, you would pour the Bourbon into an infusing jar then the grease from a pound of bacon in after. Allow to sit for 24 hours then place into the freezer so that the fat rises. When the fat coagulates (takes like an hour), simply remove it from the surface then strain it though a strainer to catch the little bits. The result is a smoky flavored infused Bourbon.
