Here is a picture sequence of how to render fat.
The oven was set at 225 degrees F. I poured off the first round of fat after 45 minutes and the second and third after 45 minutes each. Sprinkle the cracklings with salt and put on a salad, veggies or soup! Yum! I’m going to use some of the first pour off for tallow balm and soap-making and the rest for cooking. Enjoy!

Lamb fat from the butcher. Tip: make sure the fat is super cold before cutting and putting in food processor.

Cracklings!

The lovely rendered fat. I will break it up into pieces after it cools and hardens then store in the freezer.
