I pour off the fats into a can or sometimes even a mug that is lined with aluminum foil. this time it was a beet can I store it in the refrigerator
I then pour it into trays I used a mini cup cake wrapper and some take out containers I push it into the mold with the wooden spoon I used to mix with.
I will place these in the refrigerator and when the cool the will be stuck together. Now this is a soft suet and is not as hard as the type you buy.
I will use an onion bag to hold the finished suet I can hook it closed and hang it from a tree or a shepherds hook. I might just give this to my niece with a hook to hang it out side her window.
Here it is with the mini muffin bird seed suet block in the bag hung from one of the ever green out back by a window near my mothers room. Just in time for a big snow storm.
