Please forgive the subpar preview image of this. Anyhow presenting the SoonerBatchElixirs mod! This simple tuning mod allows your sim to make three potions as soon as they learn the alchemy skill. On top of that each time yor sims go to make potions they'll make three each time. Making the potions is like serving food so you be making more potions while using fewer ingredients than if you queued up a lot of mixing.
Note: You do need supernatural in order for this mod to work.
