Mojo Shrimp with Couscous and Fried Capers was both excellent and it turned out to be a major learning experience, actually 3 learning experiences. We like almost any dish that has Shrimp. We liked this one very much. The limes brought a vibrancy to the dish that I liked.
1st learning experience: we found out almost all Shrimp sold in the fish counter at the major markets were frozen.
2nd learning experience, on a whim at the NOMA pop-up store near us, I purchased a NOMA zester, mainly because I liked its design. I had a micro-plane zester I have used for years. I always noticed the grated lemon, or lime peel was extremely fine. Duh - the word Micro should have been the key. The NOMA zester was not a Micro zester and it gave perfect size zest. The guy's a creep, but he designed a great zester.
3rd Learning Experience I asked my self how do millions of shrimp get cleaned? Now I know!
We found out from after all of the these years that the shrimp in the markets are almost always frozen and they are thawed and put out for sale. I had assumed they were fresh shrimp. I know that McCall's carries fresh Santa Barbara Spot Prawns for example. But major markets don't. Since we often buy deveined, un-shelled Shrimp we now know they are almost all frozen when they arrive at the big stores. So you can buy bags of frozen shrimp and keep them in your freezer, handy to have around. Note to self, check on YouTube or CHATgpt how do commercially sold bags of shrimp get deveined and cleaned. Is there a machine for it or do thousands of workers do it manually. Well I asked AI (Gemeni in this case). Now I have the answer: Both.
From Gemeni:
It depends on the scale of processing, the origin of the seafood, and the specific variety, but across the global market, both methods are widely used.
Here is how the processing breaks down:
By Hand (Manual Processing)
Dominant in imported farm-raised shrimp: A vast majority of frozen peeled shrimp imported into North America from major farming regions (such as India, Vietnam, Indonesia, and Ecuador) is processed manually by hand using handheld tools or small blades.
Cost dynamics: In many major aquaculture hubs, labor costs remain low enough that hand-peeling is economically viable and yields a higher percentage of usable meat compared to machine processing.
Quality & control: Human workers are better at handling delicate, variable-sized shrimp without tearing the flesh or leaving behind fragments of shell and vein.
By Machine (Automated Processing)
Dominant in large-scale industrial operations: Used extensively for wild-caught domestic fisheries (such as Gulf of Mexico shrimp in the U.S.) and large commercial processing plants handling massive uniform volumes.
How it works: Industrial machinery utilizes specialized rollers, water pressure, and mechanical blades. High-speed systems place shrimp onto track feeds where a circular blade slits the back, flushes out the vein, and strips off the shell automatically.
Modern advances: Advanced processing facilities employ optical sorting cameras and automated positioning systems capable of peeling thousands of individual shrimp per hour.
| Processing Method | Typical Origin / Type | Key Advantage |
| Manual (Hand-Peeled) | Imported farmed shrimp (e.g., Vannamei white shrimp) | Better yield, cleaner finish on delicate meat |
| Automated (Machine-Peeled) | Domestic wild-caught, large-scale industrial processors | High volume throughput and speed |
When buying packaged frozen shrimp at retail, a clean, uniform slice down the back often indicates machine precision, whereas slight variations or intact tail segments usually point to hand prep.
Mojo Shrimp with Couscous and Fried Capers
New York Times
A tangy sauce of citrus, garlic and oil, mojo de ajo is one of the most popular ways to cook seafood all over Mexico, especially in breezy beach restaurants along the coast. The fragrant sea of lime juice, zest and chopped garlic, sizzling in hot oil, coats every bite like a full-on garlic bath. This version is a true one-pot meal: The shrimp is cooked in the remnants of crispy fried capers, finished with fresh lime juice and zest, and tossed with tender, chewy lime couscous with those addictive little pops of fried capers. For a heartier dish, you can warm a can of drained and rinsed cannellini beans or chickpeas; once the couscous is cooked through, fold the beans in gently—they’ll add creaminess and protein.
INGREDIENTS
Yield:4 servings
5 tablespoons extra-virgin olive oil, divided, plus more for serving
⅓ cup rinsed capers
8 medium garlic cloves, finely chopped
1 teaspoon freshly ground black pepper
1½ pounds shelled medium shrimp, deveined
Fine sea salt or kosher salt
1 tablespoon grated lime zest, plus ¼ cup lime juice (from 2 large limes)
1 cup (8 ounces) pearl couscous
1½ cups vegetable broth or water
½ cup chopped fresh mint leaves (from 1 large bunch)
½ cup chopped parsley leaves and tender stems
PREPARATION
1. Heat 2 tablespoons of oil in a large, heavy pot or Dutch oven over medium-high heat. Pat the capers lightly with a paper towel until they are well-dried, then add them to the oil. Cook, stirring occasionally, until they darken and crisp up (take care as they may pop as their moisture evaporates), 3 to 5 minutes. Remove the pot from heat. Using a slotted spoon, leaving the oil behind, transfer the capers to a paper towel-lined plate and set aside.
2. Return the pot to the heat over low. Add 2 more tablespoons oil and stir in garlic and pepper. Cook, stirring constantly, until the garlic is lightly golden brown and fragrant, 60 to 90 seconds. Add the shrimp, season with salt, and cook until they just start to curl, 1 to 2 minutes. Using a slotted spoon, transfer the shrimp and garlic to a medium bowl. Add the lime zest and juice and toss; set aside.
3. Add the remaining 1 tablespoon of oil to the pot and raise the heat to medium-high. Stir in the couscous and toast, stirring often, until golden and fragrant, 3 minutes. Stir in broth or water and bring to a simmer. Cover with a lid, and cook until the couscous is al dente and most of the liquid has evaporated, 7 to 10 minutes. Turn off heat.
4. Fluff the couscous with a fork. Stir in the shrimp and herbs. Season to taste with salt and pepper. Divide among bowls, top with capers and drizzle with olive oil if you’d like.
