Why the Humble Packet Deserves a Second Look

Britain has spent the best part of a century quietly perfecting the crisp, and yet most packets are gone before anyone has tasted them. Eaten on the sofa, on a train, or on a sea wall in a stiff easterly, a crisp is usually just a background noise. But give it ten minutes of proper attention and you find real craft: the thickness of the slice, the temperature of the oil, the way salt clings to a fried potato. Tasting them seriously is not pretentious. It is cheap, it is sociable, and it turns a Friday night into an argument worth having.

You need no equipment beyond a bowl, a glass of water and a few friends with opinions. Here is how to do it properly.

Setting Up Before You Open Anything

Temperature is the first thing people get wrong. A cold packet numbs both the fat and the seasoning, so take everything out of the cupboard or the fridge half an hour before you start. Room temperature crisps taste of more. If you are tasting by the sea, keep the packets out of the wind and weighted down with a stone, or you will be chasing them along the promenade.

• Pour each packet into its own small bowl and number them if you are tasting blind.
• Have plain water to hand. Fizzy drinks coat the tongue and flatten the finish, and milky tea does much the same.
• Keep a slice of plain bread or an unsalted cracker nearby to reset your palate between packets.
• Taste in order of strength: salted first, then sea salt, then salt and vinegar, then cheese and onion, saving anything smoky, spicy or heavily flavoured for last.
• Two or three crisps per packet is enough. More than that and your palate is simply tired.

First Contact: Reading the Crunch

Hold the crisp at one end between thumb and forefinger and bite with your front teeth, not your back ones. Listen as much as you taste. A good crisp gives a clean shatter or a bright snap that travels down the length of the slice. A dull thud, or a chew that turns waxy and claggy, usually means the crisp has taken on moisture or was fried at too low a temperature.

Look at it while you chew. Pale gold with a few darker blisters is exactly right. A faint green tinge means the potato was exposed to light before frying, and you will taste a bitter note at the edge. Very thin crisps that dissolve to nothing are pleasant but shallow; very thick ones can taste floury if the middle has not cooked through.

The Potato Underneath

Seasoning is easy to hide behind, so push it aside for a moment and concentrate on the base note. Properly fried potato tastes earthy, faintly sweet and slightly nutty, with a clean, buttery fat behind it. Skin-on crisps often carry a deeper, more savoury tone because the skin has browned along with the flesh.

Faults are usually obvious once you know what to look for. Cardboard or damp paper means old stock or poor storage. A harsh, acrid tang suggests oil that has been used too long. A raw, almost floury taste points to an undercooked slice. And if all you can detect is salt, the potato was probably never much good in the first place.

Seasoning: Balance and Coverage

Good seasoning is a conversation, not a shouting match. Ask yourself what each element is doing. Salt should lift the potato rather than bury it. A touch of acid, usually vinegar or citric, cuts through the fat. A little sweetness rounds the edges, and a savoury depth keeps you reaching for the next one. If the flavour fades after two crisps, it was never balanced to begin with.

Coverage matters as much as quantity. Tip the packet gently before opening, then check whether the seasoning is evenly dusted or whether half of it is sitting in the bottom as powder. Too much and your tongue is coated before the potato arrives; too little and the mouthful tastes flat. Sea salt, in particular, should register as bright flecks rather than a uniform grit.

The Aftertaste and the Seaside Test

Wait thirty seconds before you judge. The finish is where cheap crisps give themselves away: a greasy film that lingers on the roof of the mouth, a metallic bitterness, or a sour note that builds rather than fades. A good crisp leaves the palate clean and slightly savoury, and you should be ready for another without needing a drink.

Eat them outdoors and the whole thing changes. In sea air, salt tastes less salty, which is why a packet that seems perfectly judged in a kitchen can taste under-seasoned on a harbour wall. Seaside food has always understood this. Vinegar on chips, cockles with pepper, whelks with a little salt: the coast sharpens the appetite and dulls the seasoning at the same time. If you are tasting by the water, keep a plain salted packet as your reference point and adjust your notes accordingly.

Judging a Packet with Friends

Score each packet out of five in four categories: crunch, potato flavour, seasoning balance and aftertaste. That gives a total out of twenty and a number nobody can argue with, though they will try.

• Crunch: clean shatter and a lasting snap score high; waxy or damp scores low.
• Potato: earthy, sweet, nutty and clean. Reward flavour that survives the seasoning.
• Seasoning: balanced, well distributed, and still interesting on the third crisp.
• Aftertaste: clean and moreish. Penalise grease, bitterness and anything that lingers unpleasantly.

Compare notes out loud, because half the pleasure is discovering that your favourite scored badly and the packet you dismissed won on points. Run it again next month with a different set, and keep a notebook. Within a year you will have a personal league table, a sharper palate and a small pile of very good excuses to buy more crisps.
