Cactus Shrimp With Cactus-Lime-Butter Sauce

The first time I tasted cactus fruit, or tuna as it’s often called, was at a small roadside stand in the Texas Hill Country. The vendor, a weathered woman with eyes that held the wisdom of the desert, offered me a slice of the vibrant magenta fruit, peeled meticulously to avoid the tiny spines. The flavor, a surprising blend of watermelon and bubblegum with a hint of tartness, danced on my tongue, instantly transporting me to the sun-drenched landscape. That memory, of the intense flavor and the warmth of the Texas sun, comes flooding back every time I prepare this Cactus Shrimp with Cactus-Lime-Butter Sauce. It’s a dish that perfectly captures the spirit of the Southwest – bold, unexpected, and utterly delicious.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 25 minutes
• Total Time: 45 minutes
• Servings: 4
• Yields: 4 appetizers
• Dietary Type: Gluten-Free (if using gluten-free tempura mix)

Ingredients

• 5-6 prickly pears, dethorned if necessary, peeled, yielding 1 1/4 cup of puree (tunas, the fruit of the cactus)
• 1 (8 ounce) box tempura mix (some will be left over)
• 1 tablespoon achiote paste
• 1/2 lb large shrimp or 1/2 lb medium shrimp, peeled and deveined
• 1/4 cup cornstarch
• Peanut oil, for frying

Cactus-Lime-Butter Sauce

• 1/4 cup white wine
• 1/2 bunch cilantro, stems removed
• 1 shallot, minced
• 1 lime
• 1/4 cup heavy cream
• 1/4 lb unsalted butter, at room temperature

Equipment Needed

• Food processor or blender
• Medium-size bowl
• Heavy 2-quart saucepan
• Whisk
• Fine sieve
• Deep fryer or large pot for frying

Instructions

1. Begin by preparing the cactus fruit. Pulse the prickly pears briefly in a food processor or blender until a puree forms. Strain the puree to remove any seeds or pulp. You should have approximately 1 1/4 cups of puree.
2. Set aside 1 cup of the pureed tunas for the batter, and reserve the remaining 1/4 cup for the Cactus-Lime-Butter Sauce.
3. Next, prepare the tempura batter. Combine 1 cup of the tempura mix and the achiote paste in a blender or food processor. Pulse until the mixture is smooth and the achiote paste is fully incorporated.
4. Transfer the achiote-tempura mixture to a medium-size bowl. Add the 1 cup of pureed tunas that you set aside earlier. Mix well until a smooth batter forms.
5. Cover the bowl and chill the tempura-tuna batter in the refrigerator until ready to use. This allows the batter to thicken slightly and the flavors to meld.
6. While the batter is chilling, prepare the shrimp. Dust the peeled and deveined shrimp with cornstarch, ensuring each shrimp is lightly coated. This helps the batter adhere properly during frying.
7. Heat peanut oil in a deep fryer or large pot to 375°F (190°C). Ensure there is enough oil to fully submerge the shrimp.
8. Dip each shrimp individually into the tempura-tuna batter, making sure it is fully coated. Gently lower the battered shrimp into the hot oil, frying only 3-4 at a time to prevent overcrowding and maintain the oil temperature.
9. Fry the shrimp for 2-3 minutes, or until golden brown and cooked through. Remove the fried shrimp from the oil with a slotted spoon and place them on a wire rack to drain excess oil.
10. While the shrimp is frying, prepare the Cactus-Lime-Butter Sauce. In a heavy 2-quart saucepan, combine the white wine, cilantro (stems removed), and minced shallot.
11. Cook the mixture over medium heat until the white wine is almost completely reduced, leaving only a small amount of liquid in the pan.
12. While the wine is reducing, zest the lime using a microplane or fine grater. Set the lime zest aside.
13. Juice the lime and set the lime juice aside as well.
14. Once the wine has reduced to almost nothing, add the lime zest, lime juice, and heavy cream to the saucepan. Stir the mixture constantly with a whisk.
15. Lower the heat to a simmer and cook for 3-5 minutes, allowing the sauce to slightly thicken.
16. Remove the saucepan from the heat and let it cool for about 5 minutes. This is crucial to prevent the butter from separating when added.
17. While the pot is still hot (but not scalding), slowly begin whisking in the unsalted butter, a tablespoon at a time. Ensure each tablespoon of butter is fully incorporated before adding the next. Continue whisking until the sauce is smooth and emulsified.
18. Strain the Cactus-Lime-Butter Sauce through a fine sieve to remove any solids and ensure a silky smooth texture.
19. Keep the sauce warm. If it becomes too cold or too hot, the sauce will separate, and you’ll have to begin the emulsification process again. A double boiler or a very low heat setting can help maintain the temperature.
20. Just before serving, fold in the remaining 1/4 cup of cactus fruit puree into the warm sauce. This adds a vibrant color and a hint of cactus fruit flavor to the sauce.
21. Serve the crispy fried Cactus Shrimp immediately, drizzled generously with the Cactus-Lime-Butter Sauce.

Expert Tips & Tricks

• For extra crispy shrimp: Double-dip the shrimp in the tempura batter. Dip once, let excess batter drip off, then dip again before frying.
• Maintain oil temperature: Use a thermometer to ensure the oil stays at 375°F (190°C). If the oil is too cool, the shrimp will be greasy. If it’s too hot, the batter will burn before the shrimp cooks through.
• Achieving a smooth sauce: The key to a smooth, emulsified butter sauce is temperature control. Ensure the sauce is hot enough to melt the butter but not so hot that it causes the butter to separate. Whisk vigorously and patiently.
• Make ahead tip: The cactus fruit puree can be made a day in advance and stored in the refrigerator. The Cactus-Lime-Butter Sauce is best made fresh but can be held warm for a short period (30 minutes) using a double boiler.

Serving & Storage Suggestions

Serve the Cactus Shrimp immediately after frying for the best texture and flavor. Arrange the shrimp artfully on a platter and drizzle generously with the Cactus-Lime-Butter Sauce. Garnish with fresh cilantro sprigs and lime wedges for an extra pop of color and flavor.

Leftover Cactus Shrimp is best stored in the refrigerator in an airtight container. It will remain palatable for up to 2 days, though the batter will lose some of its crispness. The Cactus-Lime-Butter Sauce should also be stored separately in the refrigerator.

To reheat the shrimp, bake in a preheated oven at 350°F (175°C) for 5-7 minutes, or until heated through. Alternatively, you can use an air fryer to re-crisp the shrimp. Reheat the sauce gently over low heat, whisking constantly, until warmed through. Do not boil the sauce.

FAQs (Frequently Asked Questions)

Q: Can I use frozen shrimp for this recipe?
A: Yes, you can use frozen shrimp. Ensure the shrimp is fully thawed and patted dry before dusting with cornstarch.

Q: Where can I find prickly pears?
A: Prickly pears can often be found at specialty grocery stores, farmers’ markets, or Latin American markets, especially during the late summer and fall.

Q: How do I dethorn prickly pears safely?
A: The safest way to dethorn prickly pears is to use tongs and carefully singe off the spines with a kitchen torch or by holding them over an open flame. Alternatively, you can wear thick gloves and carefully scrub the fruit under running water.

Q: Can I make the tempura batter ahead of time?
A: Yes, you can make the tempura batter up to a few hours in advance. Store it in the refrigerator until ready to use.

Q: My Cactus-Lime-Butter Sauce separated. What did I do wrong?
A: The most common reason for sauce separation is temperature. Either the sauce was too hot when the butter was added, or it cooled down too much. Try gently reheating the sauce over low heat and whisking vigorously to re-emulsify it. If it doesn’t come back together, you may need to start over.
