Dagger, could you please explain the effect of adding egg whites?
Any kind of brew with particles that is really hard to filter, egg whites should clear, if done correctly.
The egg white will somehow bond will all the particles in suspension. This happens at warmer temperatures, perhaps around 60C+
If you have a brew of 50 gram rue in 1 liter of water, which you want to filter. Remove the coarser particles, and add the brew to a pot. Turn the hotplate on max heat and add the egg white. Perhaps two egg whites is needed, not quite sure with rue. Another important thing is that the brew is not too high in pH, this would prevent it from working. pH 4-5 should work.
It is important to keep the liquid moving at all times while it is heating, so keep swirling that brew with a fork or something.
As it get hotter, a reaction will start, particles will pop onto the surface. You will start to see that the brew becomes clearer. A omelette thingy will start to form on the surface. Continue to swirl until it starts to boil. Let it boil for 30-60 seconds. Then take it off.
When you now filter it, which should be easy, the brew should be crystal clear. No more particles.
