We have made this recipe a few times with slightly different variations with good results. We have noticed that the birds prefer the homemade suet over the commercially made kind.
Beware - this suet will smell so good when you are making it. You may be tempted to eat it. Bacon and peanut butter are a perfect match!
Alright. Let's feed the birds.
Total project time - including cake cooling - is under 2 hours.
Step 1: Ingredients
For this Instructable, we used bacon fat, beef suet, peanut butter, peanuts, raisins, cracked corn, and later remembered to add corn meal, oatmeal and whole sunflower seeds. We had about six cups of rendered (melted) fat and we added roughly one cup of each dry ingredient.
Step 2: Render the Fat
If you use beef suet, chop it up before melting. We used an organ grinder to get the beef suet into small pieces. The beef suet will melt quickly, too.
The fat melted in about 6 minutes.
Step 3: Combine the Ingredients and Cool
Add your dry ingredients and stir it up. Place the pot outside or in the freezer to cool until the mixture thickens. Stir the mixture periodically to keep the solids from sinking to the bottom.
Step 4: Pour Into Molds & Freeze
Don't overfill your molds. Keep in mind the dimensions of your suet cage.
Place the molds in the freezer to set - about 20 minutes.
