Tallow adds great flavor stuff too. I didn’t understand why the food my grandparents used to fix was so good compared to what my mom fixed until these last couple years where I’ve been playing with oils, and my grandparents cooked everything in lard and bacon grease. So now I save my bacon grease too. I’ve got like 3 jars in the fridge. My wife still uses olive oil mostly, but I use the bacon grease.
