David, love to share this recipe from Cher (our forum administrator)
1 cup lard & 1 cup crunchy peanut butter – melt in microwave just until smooth
Add 1/3 cup sugar into the melted lard & peanut butter
Then add dry ingredients:
2 cups quick cook oatmeal
2 cups yellow cornmeal
1 cup flour (preferably whole wheat) (optional raisins or dried fruit, mine don’t eat this)
This will be a fairly stiff dough – just stir all together – let cool and set about 5 minutes or more & then mix up again until crumbled consistency – then cool good either outside where cold or in fridge. When good & cool you can put in large zip lock bag to store, getting some out when needed. I usually feed about 1/2 cup or more two times a day – I put it in my cage feeder to exclude the large birds, which will gobble it all up immediately (I have seed feeder for them). It may take your blues a while to learn to like this, just like the mealworms, but my birds (& all other winter birds) love it. It is full of protein (peanut butter), fat to keep warm & a little bit of sugar for energy. Of course you can buy the cake suets but much cheaper to make your own) Good luck!
P.S. this and many other suet recipes are on the Sialis.org website.
