What Is Frassing?
Fringing is the name given to any type of dried insects or other invertebrates that are used as food. There are many different types of frasses, but they all have one thing in common: They’re made from insects or other invertebrates such as worms, millipedes, centipedes and spiders.
The term “fringe” comes from the fact that these foods aren’t considered to be “real” foods. These foods are usually not consumed regularly, and they’re eaten only occasionally when there’s no other option available.
Fringes come in various forms including dusts, pellets, flakes and powder. Some fringes contain animal matter such as blood or feathers; others don’t contain anything at all (like algae). Most fringe foods are high in protein and low in fat, which makes them ideal for vegetarians.
Fringe Foods That Are High in Protein And Low In Fat: Worm Castings
Worm castings are another type of fringe food that contains very little fat and lots of protein. They’re commonly found in nature, but they’re most often found in the form of tiny white worms called algaes. Algae produce their own food source through photosynthesis, so they need nutrients like nitrogen and phosphorus to grow.
For this reason, they’re often found in piles of dirt and rocks. They grow very quickly and reproduce in large numbers, so it’s easy to collect them. The easiest way is to simply dig up the ground and collect the castings.
