What are the exact dimensions of a dollop, a smidgen and a pinch?

From my grandma: a pinch is what you can grab between your finger and thumb, a smidgen is two pinches a dollop is what a teaspoon can hold when it's scooped, like a dollop of sour cream, not leveled off.

{@guywithopinions] 🤔i think a smidgen and pinch is a very small measurement 😆 a dollop is actually an insult

Ask and thou shalt receive (via Google)🤗
Who knu they were ACTUAL measurements to these !
