Is a spoon kitchen utensil used to measure an amount of an ingredient, either liquid or dry, when cooking.

This remarkable little timer uses temperature instead of time to
perfectly gauge whether a boiled egg is soft, medium or hard.
It absorbs heat exactly as an egg does, changing color from
the outside edge in to show the level of doneness.
Rest this ingenious plastic egg on the pan bottom and it will
change color as the boiling eggs progress from raw to soft,
medium or hard boiled.
Adjusts automatically to the number of eggs and the level
of water in the pot.
Easy to use.
