Yassa in Dakar: what it is, what to order and what to avoid

Overview

Yassa is meat or fish that has spent hours in lime juice and a great deal of sliced onion, then been browned and finished in that same marinade, cooked down until the onions collapse into a soft, glossy, sour-sweet sauce. It is served over white rice. The sourness is the point: a yassa should make you notice the lime before anything else, with mustard, garlic, black pepper and chili behind it, and the sweetness of onions cooked long enough to lose their bite.

It is not, strictly, a Dakar dish. Yassa is generally traced to the Casamance, the green, river-cut south of the country, and to the Diola people who live there, which makes it the capital’s adopted dish rather than its own. That origin is the conventional account rather than a documented one, and nothing like a dated recipe settles it. What is beyond doubt is that the dish traveled north long ago and became one of the handful of plates every Senegalese kitchen makes, and that Dakar, where people from every region of the country live and eat, is where a visitor is most likely to meet it.

It sits in a clear place in the city’s food. The national dish is the fish-and-rice thiéboudienne, a lunch built on tomato and slow, heavy cooking; yassa is the sharper, lighter counterpart, and on a hot day it is often the easier one to want. It is also the dish most often cooked for guests and for gatherings, partly because chicken has long carried a sense of occasion that everyday fish does not.

Two techniques define a good one. The marinade is long, often overnight, so the acid works into the meat rather than sitting on it. And the protein is browned before it goes back into the onions, traditionally over charcoal: that char is what separates yassa from chicken boiled in a lemony sauce, and it is visible on the plate as darkened skin under the onions.

What to order

The dish is named by what is in it, and the French forms are the ones on most boards:

• yassa poulet — chicken, and by some distance the most common. Expect bone-in pieces, usually a leg or a quarter, not boneless strips.
• yassa poisson — fish, often a whole small fish or thick steaks of a firm white one, grilled and laid over the onions. Lighter and more acidic, and the version that makes most sense in a fishing city.
• yassa viande — beef or lamb. Less common on a daily board and more likely at a family meal or a celebration.

In Wolof the same dishes are yassa ginaar (chicken), yassa jën (fish) and yassa yàpp (meat). Using the Wolof word costs nothing and tends to be received warmly.

What arrives is a mound of white rice with the meat or fish on top and the onion sauce spooned over everything, sometimes with green olives or a few carrot slices in it. Plain rice is the norm; the broken rice of thiéboudienne is less usual here, though not wrong. A wedge of lime and a small dish of chili paste may come alongside.

Heat is the one thing worth asking about. Home cooks tend to put the chili in the pot, while places that serve many visitors often hold it back and let you add it. If you want it the way it is eaten at home, ask for it pimenté. If you do not, the side dish is your control, and nobody will think twice about leaving it alone.

If you are invited to eat yassa at home, it may come in a single large bowl set on the floor or a low table, each person eating from the section in front of them with a spoon or the right hand. Eat from your own section, and let the host move the best pieces of meat toward you rather than reaching for them.

What to avoid

The failures of yassa are mostly failures of time, and they are visible.

Onions that are still crunchy, or pale and thin slices laid on top, mean the sauce was assembled rather than cooked. The onions should be soft, translucent to golden, and slippery, with the sauce clinging to them. A plate that is mostly white rice with a scatter of raw-ish onion and a squeeze of lemon is the shortcut version, and it tastes like what it is.

Chicken with smooth, pale skin and no color on it has been boiled in the sauce from the start. It will be tender and perfectly edible, but it is missing half the dish.

Watch for a thick or creamy sauce. A yassa sauce is loose, oily and sharp; one that coats the spoon like a gravy has been thickened or softened, and it is the version made to be agreeable rather than right. The same goes for a yassa that tastes mainly salty and savory with no sourness: if the lime has gone missing, so has the dish.

Finally, timing. In the cheap lunch places yassa is cooked in the morning and served until it runs out. A plate still offered late in the evening from the same pot has been sitting for most of a day, and the onions will have turned dark and soft past the point of good. In a restaurant that cooks to order it is another matter; the question to ask is whether the dish is made for lunch or made for you.

Practicalities

Lunch is the meal that matters. In the small canteen-style eateries Dakar calls gargotes, the day’s dish is chalked up or simply announced, and yassa may be on it one day and not the next; if it is not on today, it is not a matter of asking nicely. These places fill between about one and two in the afternoon, and the popular pots may be empty before the evening.

A plate in a gargote is among the cheapest full meals in the city; a sit-down restaurant with table service costs several times as much, and a hotel more again. At the top end you are generally paying for a bigger portion and a quieter room rather than a better sauce.

Fish yassa is easiest to find near the coast and at lunch, when the morning’s catch has been grilled; chicken is on offer all week. At celebrations and family gatherings, yassa made in very large pots is one of the standard dishes, which is also why the version cooked at home for many people is often the best one anybody eats.

Drink something cold and sweet with it, since the dish is sharp. Bissap and bouye juices are the usual partners, and a glass of strong, sweet tea afterward is how the meal tends to end.
