Does anybody have a good source for food-grade plastic tubs or bins? I'm looking for something that will hold at least 10 Gallons, maybe up to 15. Ideally round with rather large diameter (for easier dumping of the dough), Rectangular would also work. My two options locally are 50 bucks for an 18x24x9 inch tall rectangular tub (+ 15 bucks for a lid), or a 10-Gallon Rubbermaid trash can for 20 bucks (and a few more bucks for the lid).
I am trying to find "proper" sandwich pans, the type with a lid that produce a square loaf. While I am on the subject, if it does not have a lid, it is called tin bread and not sanswich.
ironically, I used to be a bakery lecturer and we had dozens of these in use all the time. Cant find one for love nor money now though!
Any ideas would be much apprecieated.
