I would guess Europeans cook more than Americans, since the average disposable income is less in Europe. Beyond that, I'm unwilling to generalize over Europe.

I would guess Europeans cook more than Americans, since the average disposable income is less in Europe. Beyond that, I'm unwilling to generalize over Europe. HN people are unlikely to be typical on either continent. I do know a European with two ovens. It's very unusual, but they really like cooking. Even so, they only use the second oven rarely -- perhaps roasting meat in one, and baking in the other. The additional oven was installed after seeing two ovens in a kitchen on a trip to the USA.
