Actually, zweibach would be the equivalent of biscotti, since they both translate to "twice baked." I am not sure, but think that "mandlebrot" might refer to "almond bread."
On the subject of socks, in learning the Spanish for "That's what it is!" it is useful to know that "Eso si que es!" pronounced S-O-C-K-S, which of course spells "socks."
