How to know your EGG is half boiled

The eggs are marked with logos in "thermochromic" invisible ink, which turns dark when it reaches a certain temperature.

Inks have been created to appear after three minutes to indicate a soft-boiled egg, after four minutes for medium and after seven minutes for a hard-boiled egg.

Shoppers will be able to buy the eggs of their choice in cartons marked "soft", "medium" or "hard".

The project was launched by the quality assurance scheme Lion Quality Eggs in response to thousands of people asking how to boil eggs properly.
