So I sent my sweetie to Spice Ace to pick up some smoked salt. Some text messaging ensued:
K: what kind of wood for smoked salt?
J: what do they have?
K: apple wood, alderwood, hickory, guava
J: guava? guava smoked salt?
K: OMG
J: what?
K: danish viking smoked salt
J: ????
J: what is is smoked with, burning villages?
K:

In the end, we got the applewood and the guava. The Danish Vikings were too expensive (maybe they did use burning villages). And the guava, really, how could you not?
