This is not your standard taco night. There is smoke and fire throughout these tacos. Mezcal, fire-roasted tomatoes, pimenton and chipotle in adobo bring the smoky heat to counter a cool crema and juicy shrimp.
For the crema: Seed and chop green chili. Halve and pit avocado. To a food processor or high power blender, add the juice of 1 lime, chili, scoop in the avocado, onion and crema or sour cream and process into a smooth sauce. Season with salt to taste.
For the tacos: Finely chop onion. Place tomatoes in a strainer to drain. Pat shrimp dry. Peel garlic and thinly slice, grate or chop garlic.
Heat a large cast-iron or wide, shallow skillet over medium-high heat with EVOO, 2 turns of the pan. Melt butter into oil and when it foams add onion, garlic, cumin, paprika and chipotle in adobo. Swirl and toss a minute. Add tomatoes, cook a minute or 2 more, then add mezcal and a drizzle of honey -- be mindful of a flare up. Swirl a minute more. Add the shrimp to the sauce, season with salt and pepper and cook, turning occasionally, 3 to 4 minutes. Add juice of lime, remove from heat.
Char tortillas in a hot stainless pan over high heat or over open flame on gas burners. Blister the tortillas 20 to 30 seconds and stack in a cloth napkin or towel to keep warm.
Serve shrimp in serving bowl with tortillas, crema, lettuce, lime wedges and toppings alongside.
To build tacos: Slather or squirt sauce on tortilla, top with lettuce, shrimp -- squirt on more lime juice of you like, cilantro, jalapenos, radishes, cheese and scallions.
