Brewing is normally used of liquids — when other types of food are boiled or simmered the term stewing is more likely to be used instead.
Brewing is stewing herbs (especially medicinal herbs) and potions, and it is often employed in legend and fiction, especially fantasy, for example a "witches' brew".
