Maybe I'm the only one patting myself on the back for this, and everybody else has been doing it for ages already....
The molasses I use for making AACT comes with a plain old cap. I used to dribble out a dollop, and twist the bottle to cut off the flow without dripping, like a bartender.
But this winter as I was washing up, it occurred to me that nowadays, most honey comes in a bottle with a flip lid spout with convenient drip-less shutoff valve like this.... I wonder if this cap fits on the molasses bottle... AND IT DID! No more drips!!
