“Almond trees can be irrigated with human urine now [March's waning Moon] so they produce sweeter almonds. Another method for sweetening bitter almonds is to shell them in hot water according to the instructions for producing almond milk, then place them in a cask filled with sweet water, allowing them to soak for nine or ten days, changing the water daily. Almonds sweeten more rapidly if placed in running water; in fact, a basket of bitter almonds placed in a rapidly flowing river will, within three days, become as sweet as any other variety. And while almond milk, nougat, and other products can be derived from almonds sweetened in this way, the oil is unusable.”
