This is a FACT!
It won’t get rid of ALL the fat, but by patting away the grease off your latkes for example, you are saving about 14 percent of the fat. Just keep in mind that this doesn’t mean you could have more of it! As it is, you should avoid greasy food but if you’re gonna have it, have a small amount, and yes, you CAN save on the fat by dabbing it away.
Have a great Chanukah and enjoy those greasy latkes!
