not sure how it works with anything other than rice as flour has a different grain so youll need more/lesa to get the relevant size…
i measurea out couscous before as i thought this waa smaller grains ao could mould better but upto thinking you need more of this to get the same weigh (375g) for 375cc. so they seemed biger than the implants I tried at MYA.
hopefully this makes sense so i would certainly try with rice to make sure xx
