Hmmm -- I have no clear idea how to cook veal, and it's too expensive to ruin, so I never buy it. I envy you those classes.

I am also interested to know that (some? all?) cholov yisrael consumers consider cholov stam able to treyf dishes, and I wish I knew on what principle that works (presumptive treyf? I mean, at that point isn't it a safek sfeika?). I guess nobody who's that machmir is likely to eat at my house anyway, though!
