I recommend melting the bacon grease in a large pan, remove from heat, and then add the other ingredients. Mix well. The mixture should have the consistency of cookie dough.
Next, put the suet into a mold or a suet log. I prefer re-using Chinese takeout containers and placing a plastic knife broken in half in the middle to make two cakes. I have also re-used the containers from suet bought at the store.
Cover the containers and place in the freezer for about an hour to set. I prefer using the Chinese takeout containers because they have lids and they stack easily. After the suet is set, it is ready for consumption. Just pop them out of the plastic containers and into the feeder.
Now all you have to do is sit back and wait for the birds to find their snack. This is the part that my cats like. No worries; they are indoor cats.
