Sounds logical, but. . . . .

Curing salts are made by dissolving salt, along with the nitrate and nitrite
and red dye and is recrystalized. Maybe the molecular structure of each
makes them combine easier?

The nitrate/nitrite fits, while the Na atoms would of course fit. Is the
dye crystallised *with* the salts though? It might be added after, as
with coloured sugars.

Not certain where the dye molecules would end up without seeing a
crystal structure; they are larger. However, is possible to
cocrystallise things that shouldn't fit together. That is a talent I
never had, despite having a PhD from a department of crystallography.
LOL they should take back my certificate!
