Neo-Quenya: The 1968 word Q. mulë “meal” (PE17/115) indicates ✱√MUL survived in Tolkien’s later writing, so I would retain ᴺQ. mulma for “fine flour”. But I would use it only for very powdery flour, and would use [ᴹQ.] pore (Ety/POR) for ordinary “flour”.
An adjective for “fine, slender” in Early Qenya word-lists of the 1920s (PE13/164). It also appeared in contemporaneous Early Noldorin word-lists as the cognate to ᴱN. minedh of similar meaning, all derived from primitive ᴱ✶miniyā (PE13/150, 164).
