The Fifth Taste on the Sunday Table: MSG for British Cooks

At Shangki Li, we are not here to turn dinner into a chemistry lesson. But we are here to say something plainly: monosodium glutamate has had a rough deal in Britain, and it is time the white powder came out of the back of the cupboard.

You have probably met MSG without knowing it. It is the savoury hit in a Chinese takeaway, the reason a bowl of noodle soup tastes deeper than its short ingredient list suggests. It is also naturally present in tomatoes, mushrooms, Parmesan, seaweed and, yes, Marmite. The manufactured version—usually sold as MSG or E621 on a label—is simply glutamate bound to sodium, made through fermentation. It does not make food salty in the way table salt does. It makes food taste more like itself.

Why Britain learned to whisper

The phrase 'Chinese Restaurant Syndrome' entered the conversation after a 1968 letter to a medical journal, in which a reader described symptoms after eating Chinese food. The idea stuck. It fitted a familiar British story: foreign food as suspicious, a takeaway as a treat with a side order of unease. Supermarkets began advertising 'no MSG' as a virtue. Restaurant menus followed. Before long, MSG had become the thing diners asked about in a hushed voice, as if the answer might change their opinion of the whole meal.

The science has moved on. Regulatory bodies in the UK, Europe and elsewhere consider MSG safe for general consumption. Some people report sensitivity, and if you are one of them, you already know to avoid it. But the broad claim that MSG is a public menace has not held up. What has held up is the marketing. 'No MSG' still sells, even when the same product is full of naturally occurring glutamate.

There is also a quieter issue. When MSG is treated as the defining flaw of Chinese cooking, the implication is that the food is somehow cheating. Nobody says that about a Parmesan risotto or a slow-cooked beef stew. The savoury note is the point. Chinese cooks have simply been more honest about it.

What it actually does

Think of MSG as a supporting actor. It does not bring its own flavour so much as amplify the savoury, rounded quality already in the pan. A pinch can make a gravy taste as if it has been simmering for longer. It can give stir-fried greens a meaty undertow without any meat. It can turn modest roast chicken pan juices into something that tastes like a Sunday.

The practical rule is simple: start small. MSG is potent, and more is not better. A quarter of a teaspoon stirred into a jug of gravy is usually enough to notice a difference. If you taste nothing, add a little more. If it tastes flat or metallic, you have gone too far—or you need acid, salt or fat rather than more MSG.

It is not a replacement for salt. Use both, but use less salt than you normally would. MSG contains sodium, and the point is balance, not a double dose. Keep it in a small jar with a tight lid, away from steam, and treat it like any other seasoning: taste, adjust, taste again.

Start with the Sunday tray

The easiest place to begin is roast potatoes. Parboil your potatoes as usual, then add a generous pinch of MSG to the water along with the salt. Drain, shake, and roast in hot fat. The result is not 'Chinese' in any obvious way. It is just more savoury, with a deeper golden edge and an interior that tastes seasoned all the way through.

Next, gravy. Whether you are making onion gravy for sausages or a Sunday chicken gravy, stir a small pinch of MSG into the stock before it reduces. Do not announce it. Just watch how the gravy rounds out. If you are making a Chinese-style gravy—soy, ginger, star anise, a little sugar—MSG is even more at home. It bridges the two traditions without a passport.

Then greens. Heat a wok or a wide frying pan, add oil, garlic and a handful of British greens—spring greens, kale, tenderstem broccoli, whatever is good. Splash in soy sauce, a pinch of MSG and a spoonful of water. Toss hard. The greens should stay bright and slightly crisp, with a savoury gloss that makes them taste like more than a virtuous side.

You can use MSG in marinades, too. A little in a char siu-style glaze for pork shoulder, or in a simple soy and honey mix for roast chicken, adds depth without altering the character of the dish. It is particularly useful in cold-weather cooking, when tomatoes are pale and stock is thin.

A pinch, not a philosophy

The goal is not to sprinkle MSG on everything and declare victory. It is to understand what it does and use it where it helps. A delicate steamed fish does not need it. A bowl of plain rice does not need it. A beef stew, a tray of roast vegetables, a pan of noodles, a jug of gravy—these are the places where a pinch earns its keep.

At Shangki Li, we cook modern Chinese flavours with British soul. That means respecting both sides of the plate. MSG is part of the Chinese pantry, and it is part of the British pantry too, whether we admit it or not. The sooner we stop whispering about it, the sooner we can get on with the good part: tasting.
