Yes, I had seen these micro-measuring spoons before. Unfortunately, some manufacturers don't adhere to those fractionals.
Norpro - 1/5 tsp, 1/11 tsp, 1/16 tsp, 1/32 tsp, 1/64 tsp.
Norpro - 1/4, 1/12, 1/16, 1/32, 1/64
RSVP - Accurate only if contents are heaped/rounded
So, since I don't know who the manufacturer is for the ones on thecheesemaker.com I got a set from amazon that was reviewed to actually measure accurately. That said, it's good to know that I can always convert to a liquid form as plan B.
Many thanks to all who replied!
