(Prompted by an interesting radio show on ducks and duck eggs).
For general uses, in either an egg-only dish, or an egg-centric dish like a custard or quiche, can I use eggs other than chicken eggs?
Other than the obvious that the volume of the dish will vary, and perhaps the cooking time, can I make a fried quail egg on toast, or a duck egg quiche? Or for that matter, to echo another recent question, a soft-boiled ostrich egg - presumably with lots of dipping toast!
