How to craft powdered grim cap

This ingredient is mentioned in a scroll:

Getting very close to the formula! Mixing a powdered grim cap with a witch flower almost works. I think I'm missing one more ingredient.

While I don't have a witch flower yet, I would be interested in how to make powdered grim cap. Maybe it is used in other recipes which I have not yet discovered. Adding different amounts of grim cap with/without flasks to the mortar did not give any results.

I mixed a grim cap, blooddrop blossom (the descritions says: Witches of the north use them in dark rituals.) and a cave nettle. What I get is a Sulphurous Potion (Rage: Attack Power +10, Evasion -10). Maybe this is meant?
