How to Make ‘DIY Suet’ That Doesn’t Melt in 80-Degree Weather (Under $0.40 a Block)

A sudden flutter of black and white wings catches my eye through the kitchen window. A Downy Woodpecker lands lightly on the wire feeder, letting out a sharp, cheerful peek call before settling in for a morning meal. The summer sun is already warming the green oak leaves, and by noon, the temperature will easily climb past 80 degrees.

Birds have a knack for bringing life and excitement into our backyards during the summertime. Black-capped chickadees are very inquisitive, while fledgling woodpeckers and glowing nuthatches excite us with their presence. All these birds have one thing in common: they fuel their high-energy lifestyles with the bird food we provide. Unfortunately for backyard bird watchers, offering bird suet feeders during the warm months presents a real problem. Most commercially available suet cakes are made primarily of raw animal fats. When the sun heats up these cakes, they become flooded with liquid fat.

Making heat-resistant suet at home is actually very easy. Simply change the ratio of fat to dry ingredients to make a safe snack that is high in energy and keeps its shape in the heat. The best part is that using bulk ingredients brings the cost down to mere pennies per block.

Why Melting Suet is a Hazard

A Note on Bird Safety: Melting suet is more than just a mess on your patio. When hot fat drips onto a bird’s feathers, it destroys their natural waterproofing and insulation. Birds cannot easily preen sticky grease out of their plumage. Furthermore, animal fats go rancid quickly in high temperatures, which can cause severe digestive issues for the flock.

Keeping our backyard visitors safe means we need to keep the food we offer stable. If a suet block starts to drip, it should be taken down right away. The purpose of a summer suet recipe is to try to get the required fats bound with enough dry ingredients to raise the melting point as high as possible.

The Secret to Heat-Resistant Suet

The trick to a no-melt recipe lies in the dry binders. We still use high-energy fats like lard and peanut butter to attract the birds, but we mix them with a heavy base of plain cornmeal, quick oats, and whole wheat flour.

These dry ingredients behave like little sponges. They soak up melted fats when mixed together. Once the mixture cools and sets, the cornmeal and the oats trap the fats, causing a dense and crumbly texture. Even when the ambient temperature increases, the dry grains hold the fats, and instead of liquefying and dripping out, the fats stay trapped.

No-Melt DIY Suet Recipe

This recipe creates a stiff, dough-like mixture. Empty plastic suet containers from the store make perfect molds, but you can also use square food storage containers or a lined baking dish.

Ingredients

Instructions

  1. **Melt the fats:** Using a large pot, set the stove to low heat, add the lard and peanut butter, and stir until the ingredients have fully melted and combined into a smooth liquid. Carefully take the pot off of the heat.
  2. Combine the dry ingredients: In another large bowl, whisk the cornmeal, quick oats, and whole wheat flour together.
  3. While stirring with a robust wooden spoon, pour the dry blend gradually into the melted fats. The mixture will be thick and crumbly, like wet sand.
  4. Press the mixture into the molds that you have selected. To do this, you may use the back of a spoon or your hands to press the mixture evenly and firmly. It is crucial to pack the mixture tightly to make sure that the blocks don’t crumble apart.
  5. Set and store: Place the molds in the freezer for at least two hours to set. Once frozen solid, pop the blocks out of the molds. Store them in an airtight container or freezer bag in your freezer until you are ready to use them.

Summer Feeding Best Practices

Regardless of having a heat-resistant recipe, summer bird feeding has a few extra precautions to keep your flock of birds healthy.

  • Find deep shade: Always hang your suet feeders where the protection of shade is maximum in your yard. The deep shade of a mature tree protects the suet from afternoon sun.
  • Consider offering smaller portions: Instead of putting a full block out, try putting out a half block instead. Birds will finish a smaller portion quicker, and will help keep the food from sitting out in the humidity for too long.
  • Clean feeders weekly: Summer heat accelerates bacterial growth. Wash your wire suet cages with hot, soapy water at least once a week. Rinse them thoroughly and let them dry completely before refilling.

Enjoying the Summer Flock

Watching a parent woodpecker bring its fledglings to the feeder is one of the greatest joys of summer birding. By taking a few minutes to mix up this simple, heat-safe recipe, you provide a reliable source of energy for the birds without risking their health. Keep your binoculars close by, listen for those cheerful calls, and enjoy the vibrant life visiting your backyard this season.
