Hi CH's and Riley, Good to hear from you again! >Ok Cameron, I'll bite. As long as it doesn't involve petroleum ether and >Soxhlet extractors I'd be interested. Replacing beef fat with a >healthier fat would be a nice trick for a nice treat. Sorry, it's 10/31. Put your stainless mixer bowl in the fridge for a while. Hell, you might as well put the ground beef in it too. With a flat beater. When good and cold, take out of the fridge and run the mixer at medium speed. The fat will stick to the walls of the bowl as it comes into contact with the cold metal. -- -- Regards, Cameron
