Do you know of a convenient dispenser for sugar by the spoon or half spoon? I'm going to make some Truvia substitute for a friend who uses individual packets for drinks because it will save quite a bit on cost (she uses a lot.) But she needs a convenient dispenser to place by her chair (hard for her to move around.) I was thinking of something near spill proof and she said she had once seen a dispenser that you turn upside down and it measures a portion? Sounds familiar, know of something?
