Use the best-quality eggs you can afford. Remember: the better the quality, the better the flavour. You can tell whether an egg is fresh by cracking it on to a saucer. If the yolk stands up and the white isn't watery, it's as fresh as a daisy. The simplest way to store eggs is in the box you buy them in. Egg shells are porous and can absorb the odours of other foods so try to keep them away from anything strong-smelling, like fish.
