👨🍳 Instructions
-
1
Preheat your oven to 425°F (220°C). Spread the rock salt evenly across a large baking sheet; this will keep the oysters stable and retain heat.
-
2
On a dry comal or skillet over medium heat, toast the Guajillo and Árbol chilies for 30-60 seconds per side until fragrant but not burnt. Place them in a bowl of hot water to soak for 15 minutes.
-
3
In the same skillet, roast the tomatoes, onion, and unpeeled garlic cloves until they develop dark charred spots. Remove the garlic skin once softened.
-
4
In a high-speed blender, combine the soaked chilies (discard soaking water), roasted tomatoes, onion, garlic, chipotles in adobo, stock, lime juice, and oregano. Blend until completely smooth.
-
5
Strain the sauce through a fine-mesh sieve into a bowl to ensure a silky, professional texture. Discard any remaining solids.
-
6
Heat a small saucepan over medium heat with the olive oil. Carefully pour in the blended sauce (it may splatter) and simmer for 8-10 minutes until it thickens and the color deepens to a dark brick red.
-
7
Whisk in the butter to the sauce to add a glossy finish and mellow the heat. Season with salt and pepper to taste, then remove from heat.
-
8
Shuck the oysters carefully, keeping as much of the natural 'liquor' (juice) in the shell as possible. Run your knife under the oyster meat to detach it from the shell.
-
9
Place the shucked oysters on the prepared salt-lined baking sheet. Top each oyster with a generous tablespoon of the Diabla sauce.
-
10
Slide the baking sheet into the oven and bake for 5-7 minutes. The oysters should be just firm and the sauce should be bubbling slightly at the edges.
-
11
Remove from the oven and immediately garnish with finely minced red onion and fresh cilantro.
-
12
Serve immediately while piping hot with fresh lime wedges on the side.
💡 Chef's Tips
Always use the freshest oysters possible; they should smell like the clean ocean breeze, never 'fishy'. If you prefer a milder sauce, remove all seeds from the Chiles de Árbol before blending. Straining the sauce is the 'chef's secret' for a luxurious mouthfeel that separates home cooking from restaurant quality. Don't overcook the oysters; they should remain plump and tender, not rubbery. If you don't have rock salt, you can use crumpled aluminum foil to stabilize the oyster shells on the tray.
🍽️ Serving Suggestions
Serve with a cold Mexican Lager or a crisp Sauvignon Blanc to cut through the spice. Accompany with warm corn tortillas or crusty bolillo bread to soak up the extra sauce. A side of white rice or a simple avocado salad provides a cooling contrast to the heat. For a truly coastal experience, serve alongside a fresh shrimp ceviche. Offer extra bottled hot sauce like Huichol or Cholula for those who want even more 'diabla' in their dish.
