Spotted some Quail eggs in M. K. Retail the other day, and thought I would try it out. Tasty, but did not seem very different to my palate from hen eggs though.
Will try some other variations maybe, like this nice one with soft-boiled eggs with Potato galette (recipe).
Quail eggs seem to be a common part of South East and East Asian street food, as well as gourmet delicacies in continental cooking like the photo above.
But wife still looks at me like she has seen a monster when she catches me looking at these wee eggs hungrily.
