Okay, the American ambassador upped the gag ante when he made the perfect cup of coffee with instant. I presume it was tongue-in-cheek, but you never know.
The perfect cup of coffee involves fresh-ground Costa Rican coffee. Unfortunately, that isn’t available in the US (I know, I asked the Costa Rican husband of a colleague). A good Hawaiian brew (I have Kauai and Lion in the pantry, honestly Kona coffee doesn’t do it for me) is a distant second.
