One of the things I have learned to love living here in Catalunya is dunking cookies in my tea.
My understanding of the etiquette on this topic is that it is really something of a no-no, at least in my family, and it was not something I ever really did. In fact even after many years here I didn't do it ever. Then a couple of my students were talking about how delicious it is, and I started dunking.
O my goodness. Love it.
Everyone here does it, especially at breakfast, it is polite and accepted. You can dunk into coffee, tea or hot chocolate, and you can dunk just about anything sweet and bread-like from cookies, to croissants to special finger like cakes made specifically for dunking, and then there are xurros!!!
I may have trouble when I go back to Canada this summer resisting the temptation!!!!
