Eggs. Poached or fried here are tips for keeping them firm
Cider vinegar added to the water when you are poaching eggs will keep them lovely and firm.
If you like fried eggs with a little bit of tough texture, sprinkle salt on while they are cooking to harden the outer portion of the egg. If you like a soft egg, do not add salt.
If you break an egg on the floor while putting them in the pan, pour salt over the area and the egg won't spread out as far so you can clean it easily!
