Meat Cutting Lecture Day 5

[@baconacresfarm9]

good info. Love your lectures. Found this on the meaning of saltpeter. saltpeter (n.) "potassium nitrate," c. 1500, earlier salpetre (early 14c.), from Old French salpetre, from Medieval Latin sal petrae "salt of rock," from Latin sal "salt" (see salt (n.)) + petra "rock, stone" (see petrous). So called because it looks like salt encrusted on rock.
