noun
granule
GRAN-yool/ˈɡrænjuːl/
A tiny grain or particle of a substance.
Tiny sugar granules fill the spoon and scatter across the surface.

Etymology
The grain root and diminutive ending make a granule literally a “little grain.” That image applies to a tiny discrete particle, whether or not it is an actual cereal grain.
In context
I've taken one granule and placed it in my mouth and grind it between your teeth. It's that little bit chalky. It needs that little bit longer. Rice like pasta should always be served al dente.
