The short answer
Yet is a Senegalese seasoning made from a large sea snail, a marine mollusc, that is cleaned, fermented and dried into a hard, intensely pungent piece. Also spelled yeet, it is used in very small amounts, much like the fermented fish guedj, to give ceebu jen (thieboudienne) and stews a deep, funky, savoury umami. A little goes a long way, and its strong aroma mellows as it cooks, leaving a rich depth of flavour rather than an overpowering one. In the UK you can find yet and other West African seasonings at African food shops, which you can find near you on African Stores.

Open a packet of yet in a Senegalese kitchen and there is no mistaking it. That deep, briny, fermented smell is the smell of a proper ceebu jen coming together, the everyday centrepiece of Senegalese cooking. For many Senegalese and Gambian families in Britain, that pungent little piece is the secret behind a pot that tastes like home, the flavour a mother or grandmother reached for without a second thought.
There is real heritage in yet. It belongs to a long coastal tradition of preserving the sea's bounty by fermenting and drying it, turning a humble snail into a prized seasoning that keeps and travels. To add a knob of yet to the pot far from Dakar or Banjul is to carry that tradition forward, and to serve someone their first plate of rice and fish deepened by it is to share a taste that is unmistakably Senegalese.
What Yet Actually Is
Yet is a traditional Senegalese seasoning made from a large sea snail, a marine mollusc, that has been cleaned, fermented and then dried until it becomes a hard, dense piece. The fermenting and drying concentrate the flavour enormously, so what you end up with is not a food to eat by the plateful but a powerful flavouring, used a little at a time to season a whole pot. It is sometimes spelled yeet, and it sits alongside guedj, the fermented and dried fish, as one of the cornerstone umami seasonings of the Senegalese kitchen.
What makes yet special is the intensity and character of its savour. It is strongly aromatic, unmistakably funky and briny in the way that well made fermented foods are, and it carries the deep, mouth-filling umami that gives Senegalese cooking so much of its distinctive depth. On its own it is pungent and very salty, which is exactly why it is used in tiny amounts. Dropped into a simmering pot, that sharp aroma softens and mellows, melting into the dish and leaving behind a rich, rounded savour rather than any single loud note. It is the kind of ingredient you notice most when it is missing.
How Yet Is Used in the Kitchen
Yet is a seasoning, not a main ingredient, and it is treated with respect in the pot. A small piece is broken off and added while a dish cooks, often soaked or rinsed first and then simmered so it can slowly release its flavour into the sauce or stew. Because it is so concentrated and so salty, cooks add it carefully and adjust the rest of the seasoning around it. The goal is depth, that savoury backbone underneath the tomato, onion and spice, rather than a fishy or snaily taste in itself.
Its most famous home is ceebu jen, also written thieboudienne, the celebrated Senegalese dish of fish and rice cooked in a rich tomato sauce that many consider the national dish. A little yet, often used together with guedj, is one of the flavours that makes a ceebu jen taste properly Senegalese, giving the sauce and the rice that unmistakable savoury complexity. Beyond ceebu jen, yet finds its way into other stews and sauces where a cook wants that same deep, fermented richness. It is one of the quiet building blocks of Senegalese food, part of a wider West African and Senegambian tradition of using fermented seafood to season everyday cooking, a taste shared closely with The Gambia.
Why Yet Matters in Senegalese Cooking
Yet matters because it is one of the flavours that defines the Senegalese table. Coastal Senegal has long looked to the sea, and preserving seafood by fermenting and drying it is both a practical way to make it keep and a way to create something new and prized in its own right. Yet is a fine example of that ingenuity, a humble mollusc transformed into a seasoning that home cooks treasure and that gives beloved dishes their soul.
For Senegalese and Gambian families, and for the wider community across Britain, yet is a link to that heritage. It is not fancy or expensive, but it is the sort of ingredient that separates a good pot from a truly authentic one, and knowing how to use it well is part of knowing how to cook the food properly. That is why cooks seek it out, and why a plate seasoned with it tastes so much of home.
Where to Buy Yet in the UK
Yet is a specialist seasoning, so the place to find it is an African food shop, especially one serving Senegalese, Gambian or wider West African customers. It is usually sold as hard, dried pieces, often alongside guedj and other dried and fermented seafood, and because a small amount lasts a long time, a single piece will season many meals. If you are shopping for it, remember that it is a shellfish product, made from a mollusc, which matters for anyone with a shellfish allergy, and that it is very salty and pungent, so you only ever need a little. When you find it, store it well wrapped so its strong aroma does not spread. You can find African food stores near you to track down yet and the other seasonings that make Senegalese cooking sing.

What does yet taste like?
On its own yet is strongly aromatic, briny, funky and very salty, the way well made fermented seafood is. Used a little at a time in a pot, that sharp aroma mellows as it cooks and melts into the dish, leaving a deep, rounded, savoury umami rather than an overpowering fishy note. It gives depth and complexity rather than a taste of snail.
How do you use yet in cooking?
Yet is used sparingly as a seasoning. A small piece is broken off, often rinsed or soaked first, then added to a dish and simmered so it slowly releases its flavour into the sauce. Because it is so concentrated and salty, cooks add it carefully and season the rest of the dish around it. It is most famous in ceebu jen, the Senegalese fish and rice dish.
Is yet suitable for people with a shellfish allergy?
No. Yet is made from a sea snail, which is a mollusc, so it is a shellfish product and should be avoided by anyone with a shellfish or mollusc allergy. It is also very salty and pungent, so even those who can eat it use only a tiny amount at a time to season a dish rather than eating it directly.
Where can I buy yet in the UK?
Yet is a specialist ingredient, so African food shops, especially those serving Senegalese, Gambian and West African customers, are the place to buy it, often sold as dried pieces alongside guedj. Because a little lasts a long time, one piece goes a long way. African Stores lists African and Caribbean food shops across the UK, so you can find one near you that stocks it.
