For Me, "Prep" has taken on a dual meaning. Since I am STILL Scheduled for Gastric Surgery at end of Month, I am trying to experimentally determine how to convert over to Espresso From the (Quart) Cup of Morning Coffee, to limit liquid intake. Slow going.
Grinding, Tamping, Pressure to use, Amount of Beans to Grind, Amount of Water, all are variables. Haven't definitively settled on even One Variable yet.
