01The most flexible thing in the fridge — four directions for a half-dozen, and how to know if they're worth cooking
In Britain, eggs are sold by size and date-stamped with a best-before.
02What You're Working With
A box of six eggs is, in practice, several different meals waiting to be named. They are the thing you grab when there's nothing else, and also the thing you reach for when you want something genuinely good. No other single ingredient swings that range — from a bowl of pasta that tastes as if it took effort to a set custard that will impress almost anyone.
Before anything else, though, freshness. An egg changes as it ages: crack a fresh egg onto a flat plate and the white clings close and proud around the yolk. An older egg spreads thin and flat, the yolk more easily broken. Neither is unsafe to eat (provided the egg has been kept cool and the shell is intact), but a fresh egg fries better, poaches better, and holds together in ways an older one won't. The classic float test — drop an egg in cold water, fresh eggs sink, old eggs rise — is a reasonable guide, though a slightly tilted egg is not a reason to throw it away. When in doubt: crack it, smell it, look at it. A bad egg announces itself immediately.
In Britain, eggs are sold by size and date-stamped with a best-before. In most of Europe and the UK, eggs sit on an unrefrigerated shelf; the eggs are not washed, so the cuticle that seals the shell stays intact and they don't need cold storage. In the United States, commercial eggs are washed and refrigerated from the outset, which strips that cuticle and means they must stay cold. Know which you're buying, store accordingly.
03Four Things to Cook
A frittata. This is where most of a box belongs — four or five eggs beaten with a pinch of salt, whatever is soft or wilted in the vegetable drawer, and a hard cheese grated over the top. The technique that matters: get the filling warm in an oven-safe pan first, pour in the eggs over medium heat, and let the base just set before the whole thing goes under a grill or into a hot oven to finish the top. Twelve minutes, start to finish. The weeknight frittata formula covers the ratio in full, but the rough rule is: four or five eggs, one pan, whatever you have.
A proper carbonara. Two eggs — one whole, one just the yolk — beaten with a fistful of finely grated Pecorino Romano (Parmesan works, or a mix of both), plenty of cracked black pepper, and a splash of starchy pasta water to loosen the sauce into something glossy rather than scrambled. The egg proteins cook on residual heat alone; the pan should be off the flame when the sauce goes in. Guanciale is the traditional cured pork cheek used in Rome, though pancetta is far easier to find and produces a fine result. This is weeknight food that takes twenty minutes and tastes like a decision.
Custard. Four yolks, a generous pour of whole milk or cream, sugar, and a flavouring — vanilla being the obvious one, but a strip of lemon zest or a bay leaf both work well. Warm the milk gently, whisk the yolks with the sugar until pale, pour the warm milk slowly into the egg mixture (this is tempering — it prevents the eggs from scrambling), then return the lot to the pan over low heat, stirring constantly, until the custard thickens enough to coat the back of a spoon. It should never boil. Poured warm over anything roasted or baked, it is one of the most satisfying things a home cook can make from scratch.
A fried egg worth eating. One egg, a thin layer of olive oil or butter in a cold pan, heat brought up slowly until the white just sets and the edges barely blister. Salt goes on early — it seasons the white and helps it set evenly. Serve on yesterday's bread, a bowl of yesterday's grains, or directly beside whatever you've just pulled from the oven. Speed is not the point here; patience is.
| Figure | What it's for |

| 4 eggs | yolks needed for a basic custard batch |
| 2 eggs | whole egg plus one yolk for carbonara sauce |
| 4–5 eggs | typical quantity for a single-pan frittata |
04A Note on What to Buy
The label does a lot of work on an egg box. Free-range and organic certifications are the clearest indicators of how a bird has been kept; barn-reared sits below these in terms of space. Yolk colour is affected by diet — a deeper orange yolk generally comes from a bird with access to pasture — but colour alone isn't a quality guarantee. Buy the best eggs you can consistently afford. They're one of the few ingredients where the difference between the cheapest and the best is immediately, plainly visible in the pan.
