Crisp Hash Browns

What to expect

Taste

Potato and salt and almost nothing else, which is the entire proposition. Fried potato tastes of fried potato — sweet, starchy, and with a distinct toasted note from the browning — and there is nothing else in the pan to interfere. Salt is the only seasoning and it needs to be assertive. Whatever fat you use is the second flavour and is the main reason for choosing dripping or clarified butter over a neutral oil.

Aroma

Frying potato, which is a specific and appetising smell that arrives about three minutes in and is the smell of a breakfast counter. Very little else.

Texture

The whole dish is a texture and it has two parts: a shattering crisp exterior and a soft, almost creamy interior where the shreds have cooked through and their starch has gelatinised. Getting both at once is the difficulty, and both preparation steps exist to make it possible — starch removed so the interior does not go gluey, water removed so the exterior can crisp. It is at its best for about three minutes.

Sound

The sizzle is the doneness cue. Cold wet potato in hot oil makes a lot of noise; as the water goes, the sound drops and turns drier and higher, and that change is roughly when the crust is forming. And then the fork through it, which should crack.

How the flavour moves

Crust first, salty and toasted. Then the soft interior, sweet and starchy. It is a short and entirely satisfying arc with no complexity in it at all, and none is wanted — it is there to be a texture beside something else.

Serve it

Very hot and immediately. There is no dish in this collection with a shorter window — a hash brown that has sat for five minutes has steamed itself soft from the inside.

Goes with

Eggs of any kind, and a runny yolk in particular, which is the best possible thing to have next to something this crisp. Bacon. Beans. Hot sauce. Ketchup, which is traditional and which nobody should feel bad about. It is a side dish and it does not want to be anything else.

Cook's notes

Difficulty

Easy, with two unglamorous preparation steps that decide everything and one instruction that is harder than it sounds: leave it alone in the pan.

Cost

Almost nothing. 800g of potatoes.

Equipment

A box grater, a clean tea towel for wringing, and a heavy frying pan — heavy matters, because a thin pan drops in temperature the moment cold potato hits it.

When to make it

Breakfast, weekends.

Best season

None.

You know it is done when

Deep gold and evenly browned, and the edges lifting slightly away from the pan. If the surface is pale and patchy, the pan was not hot enough or it was disturbed.

And it feels like

It should hold together as a single piece when turned and shatter under a fork. A hash brown that bends rather than breaks has too much water in it.

Food safety

Nothing to manage.

Where it goes wrong

Not wringing hard enough, which is the fault — wet potato steams and never crisps. Skipping the rinse, which gives a gluey interior. Waxy potatoes. Moving it about in the pan before the crust has formed, which is the instinct and is exactly wrong. Too little fat. And making it too thick, so the outside burns before the middle is cooked.

If it does go wrong

Soggy: not dry enough, or the pan was not hot enough, or it was too thick. Gluey inside: not rinsed. Falling apart when turned: no crust formed yet — leave it longer. Burnt outside and raw inside: too thick, or the heat too high. Grey: the potato oxidised before it went in, which the cold water rinse prevents.

Making it ahead

Grated, rinsed and wrung potato can be kept in the fridge for a few hours under a damp cloth, or frozen in portions. The frying is to order and always will be.

Keeping it

It does not keep in any useful sense.

Reheating

In a hot dry pan, which crisps it again reasonably well. Never a microwave.

Freezing

Squeezed raw grated potato can be frozen in portions and fried from frozen, which works and is what commercial hash browns are.

Leftovers

There should not be any. Cold hash brown is genuinely unpleasant.

Scaling it

Badly in one pan, because the whole thing depends on a thin even layer in contact with hot metal. More people means more pans or more rounds.

Substitutions

Clarified butter or bacon dripping in place of the oil is a real improvement in flavour and has the same high smoke point. Ordinary butter alone will burn before the hash browns are cooked. A grated onion squeezed dry with the potato is a common addition and makes them noticeably harder to crisp, since onion holds a great deal of water.

Dietary swaps

Vegan, vegetarian, dairy-free, gluten-free and nut-free as written, with nothing to adapt.

Shopping for it

Floury potatoes — Maris Piper, King Edward, Russet. Nothing else needs thought.

Keeping the cost down

It is already about as cheap as food gets. Save bacon fat for frying them, which is free and much better than oil.

Sustainability

Very low impact. Potatoes are among the most efficient crops there are.

Nutrition

Around 260 calories a serving, most of it the oil absorbed during frying — and how much that is depends almost entirely on how hot the pan was, since hot fat seals and cool fat soaks in. Potatoes themselves are a genuinely good source of potassium and vitamin C.

Worth it?

Worth it, and it is the cheapest transformation in the collection — 800g of potatoes and twenty minutes of preparation produce something better than any frozen version. The two steps that get skipped, rinsing and wringing, are the whole recipe. Once it is in the pan, leave it alone.

Where it comes from

Origin

The United States.

Also called

Hash browns, from hashed brown potatoes, which is how they appear in nineteenth-century American cookery writing.

Said out loud

As it looks.

What the name means

Hashed means chopped — the same root as the hash in corned beef hash, from the French hacher, to chop. Brown describes what happens to them.

History

Hashed brown potatoes appear in American cookery writing from the 1880s onwards and belong to a family of dishes built on using up cooked potatoes — home fries, corned beef hash, and the various regional hashes. What is worth understanding is the starch. A potato's cells are packed with starch granules; when they are cut, some of that starch is released onto the surface, and it is that loose starch which glues shreds together into a solid mass when heated. Rinsing removes it. The water inside the cells is the other problem, and it is simple physics: as long as there is free water in the pan, the temperature is pinned at 100°C, and browning does not begin until well above that. So the two preparation steps address two entirely different obstacles, which is why doing only one of them gives a disappointing result.

Why it matters

It is one of the fixed items of the American diner breakfast, alongside eggs, bacon and toast, and the question of whether a place makes its own or uses frozen is a reasonable proxy for how seriously it takes the rest of the menu.

When it is eaten

Breakfast and brunch.

The traditional way

Pressing into hot fat and leaving it alone. The instruction not to move it is the one people find hardest and it is the difference between a crust and a scramble.

How it changed

It was industrialised comprehensively. The compressed rectangular patty most people picture is a frozen product and is a genuinely different thing from a pan of loose fried shreds; both are called hash browns and only one of them is what nineteenth-century recipes describe.

Regional variations

American hash browns are shredded; American home fries are diced and often include onion and pepper. Swiss rösti is the same idea with a longer history and is usually made from par-boiled potato, which gives a different and slightly waxier texture. The Jewish latke is a close relative with egg and flour bound into it.

How this version differs

It rinses as well as wrings, which not every recipe does and which is the difference between a crisp shell over soft potato and one over glue.
