It would be really cool if you could help your fellow cooks by making things we still need. Things like salted butter, tomato sauce, and raisins are lower level synths that higher level culinarians need. You could def make gil on the butter at least even if you aren't getting much exp.

side note: yes you can buy butter cheap from an npc but not in Uldah, so you cash in on peoples laziness

graduate to pie dough and the vinegars (cider, dark)...and youll be into the 21-30 lvl synths and have much cooler things to make. (also... love mooglebox... but love mozk-tabetai more This is all assuming you're like me and would rather make stuff people can use then grind out sand endlessly.

happy cookin
