We will settle the plasma nonsense:
1 - The blood type of plasma:
" When separated from the rest of the blood, plasma is a light yellow liquid. Plasma carries water, salts, and enzymes. The main role of plasma is to take nutrients, hormones, and proteins to the parts of the body that need it. Cells also put their waste products into the plasma. "
I would not recommend eating this kind of plasma
2 - "characterized by the presence of a significant portion of charged particles in any combination of ions or electrons. It is the most abundant form of ordinary matter in the universe, mostly in stars (including the Sun), but also dominating the rarefied intracluster medium and intergalactic medium."
I would also not advise any kind of plasma consumption of the above.
Custard is not a plasma.
