Hello all, unfortunately, there aren't a lot of forums for beginner soba makers so I thought I'd post my question up here since my question pertains to equipment we both have in common. I need a large kneading area and I was thinking of purchasing a 3/4 inch sheet of plywood and cutting it to the required size (4'x4').My concern is whether the adhesives that hold the plywood together would potential contaminate my dough as I knead it?Are there any "food safe" plywood boards out there? Thanks in advance.
