A silky, mildly spicy sauce made from roasted poblano peppers blended with cream, garlic, cilantro, and lime. Perfect for tacos, enchiladas, grilled meats, pasta, or roasted vegetables—ready in about 20 minutes.
Roast poblanos under a broiler (or over a gas flame), turning until skins are blistered and blackened, about 8–10 minutes.
Transfer hot peppers to a bowl and cover to steam for 10 minutes to loosen skins.
Peel off skins, remove stems and seeds, and roughly chop the roasted poblanos.
In a skillet over medium heat, melt butter. Add onion and cook until translucent, about 5 minutes. Stir in garlic and cook 30–60 seconds.
Add roasted poblanos, sautéed onion and garlic, cream (or crema), cilantro, and lime juice to a blender. Blend until completely smooth. Season with salt and pepper.
Return sauce to the skillet and warm over low heat until gently simmering and slightly thickened, 2–3 minutes. Do not boil. Serve warm.
