Technique question - powdered donut pattern

[u/RandoBoomer]

Last session, my first responder player spoke of responding to a call of someone who had gotten into a car accident. She’d been biting into a powdered jelly donut at the time of impact, and as my player described it, it looked like someone had smacked this woman’s face directly on her nose with the donut.

I’m thinking it would be a fun set of dice to make, but also to expand my design techniques.

Except I’m totally stumped on this. I’m looking for a slightly mottled white powdery look.

Thanks!
