Normally in the Netherlands we use grams.
We have to weight everything.
But I'm also owner of measuring cups & spoon.... which I find soooooo much easier.
So since I really started baking and trying Enlisch/US recipes, I started using the cups.
I've got plastic and aluminimun.
(I even made my own recipes in cups because they are easier.)
And when in doubt, or a grams recipe, I use this site to convert the grams to cups :)
