NUTS Qual a noz que não cresce numa nogueira? A avelã. Although I see that in PT-BR nogueira can also be the name of the the fruit of the nogueira as well as noz. So is this a PT-PT / PT-BR issue? I think noz means both nut and walnut depending on the context. In this context it must mean walnut because no one is going to have a recipe in which any nut will do. That rule only applies to politics.
