My last 2 gallon cheese was a little big for my 5" mould and had some bulging/cracking issues... so I've been looking around for a 6" mould, to make my 2-3 gallon (and maybe 4 gallon!) cheeses in. They are rather hard to find in that size!! The Tomme seemed a little big (7 1/2"). So I took a trip to The Container Store and found a nice round 6" Polystyrene (#6 PS; food grade) container with nearly vertical walls (only 1/4" difference in top and bottom circumference) for 12 bucks. A little pricey for a Tupperware, but not so bad for a cheese mould.
I poked holes using 2 methods I've seen suggested on this forum: a hot nail on the bottom drain holes, and a drill on the sides. The drill holes are way cleaner- but from what I read, the hot nail holes may end up being more sanitary. I cut a follower out of a cheap cutting board with a Sawzall.
I think it came out pretty well- will test drive it on some cheese this weekend.
BTW, Walmart sells a stainless steel ~6" utensil holder for $6.93, if you have the materials and skills to drill stainless...which I don't....
... and if you don't mind a bottom on your mould!
