So this is a clusterfuck.

Servingspoons are used to serve up food.

Tablespoons are the largest spoons used for eating but according to the term is now used by many english speaking regions the same way as serving spoon. 15 ml in volume typically

Dessertspoons are used primarily for desserts but also for soup and other stuff. 10ml in volume typically

Teaspoons are used to stir tea and coffee. 5 ml in volume typically.

I only know serving spoons, tablespoons and teaspoons. Desert spoons are in the middle and I have probably a similar sized spoon but never known there is a difference. To me it is a smallish tablespoon. But that is where the confusion is coming from. For some the scale just shifted up or down depending on the way you are looking at it.

Yeah this should be standardized. 🥲
