Eggs

I knew eggs can be cracked, boiled, scrambled, baked in the oven, fried or cooked in the shell, tempered, beaten, hard-cooked, microwaved (with some caution)...
I knew they can be eaten raw, they can be decorated...
I knew the white can be whipped while the yolk can add a shade golden to buns or pies...
I knew they can be an inexpensive healthy choice, because of the essential nutrients/low calories content...
In Singapore, I also saw salted duck eggs, coated with a past of salt and mud or clay, and "century eggs" - thousand-years-old egg - also preserved by fermenting in a mixture of clay, alt, wood ash, lime and rice straw during one month or even more!

I recently found out that eggs can be "unwrapped": I mean, instant eggs in a plastic "shell"...
