Maybe GP's mention of "boiling salt" does not refer to "table salt" but salt in the more general chemical sense. Perhaps they use Ethylammonium nitrate with a boiling point of 240 C (464 F).

Can you find that at a grocery store?
I usually order it here: https://store.p212121.com/ethylammonium-nitrate/
