I want to buy some Staub cookware online and can't check them out myself. Are Staub pans and pots good for glass cooktop? I'm sure they would work, but for a cookware to be efficient on a glass cooktop, it must touch it with whole surface, not just on edges.
Can enyone tell me if Staub cookware have smooth and perfectly flat bottom when tested with ruler? Are they all stable on a flat surface or is it different with each piece?
