Ever use a recipe that asks for a pinch, a dollop, smidgen, or a trace of an ingredient? It would be no problem if you were a chef, and used to these amounts on a daily basis. I’m what you call a home cook, or used to be anyway, and was used to eyeballing amounts.
When shopping with a friend in a kitchen shop, I found a set of measuring spoons that included these measurements. Cool item to have “just in case”.
