It was actually a black and white stone carving. We had to do a pencil rubbing, imprinted that on another piece of paper and sent it off to be digitally enhanced and then printed in the colour you see before you.

No problems! If you end up making them, let me know :)

You've got to work out the surface area of the interior and exterior of the egg and then extract the volumetric square footage in metric imperial flombles.

The difficulty my aunt had when writing down my nan's recipes is that, in a lot of cases, she had the measurements in her head. So, there was a lot of guess work and estimation.

My guess was always that it would be half of an eggshell, previously used, twice. So, maybe it would technically be 1 egg worth of water. Never really considered that before...
