This is a method for amyloid which also demonstrates eosinophils bright red.
Paneth cell granules are also stained.  Depending on the species, elastic
fibres may also be coloured, and I have no idea whether cattle elastic will

The staining solution has some sodium chloride in it.  This is to overcome
electrostatic repulsion and is almost certainly not needed if the target is
eosinophils, which presumably stain ionically.  Leaving it out will make the
stain darker and the solution will last longer.
