Okay, so I'm now going on a weird pizza making frenzy. But before I start, I want to know: When you make flour in a windmill, then just leave it there (don't put it into a pot), does it stay there? forever? Cuz then I could just make a ton of flour, and use it for pizzas later. Anyone know?

I haven't used it for quite sometime, but I'm pretty sure it stays there, as in stacks.

Yeah that works, I made a ton of wheat since my f2p years and it's still there :/

 

I'm too lazy to take in into pots.

It works

I think that you can only stock ~28 portions of flour in the windmill, before it gets full and you can't wind another wheat stack.

 

Not sure on the number.

28 is the limit.

If you're a member, head over to the Sinclair Mansion (members Murder Mystery Quest, north of Camelot). There's a barrel full of flour in there, which can provide an unlimited number of pots of flour. It's faster to bank if you've got a lot of banked pots than actually going through the process of making the flour in a mill.

If you're a member, you might consider simply going to the Warrior's Guild and buying pre-made plain pizzas there for only 200 gp with unlimited stock, and add your toppings to those.
