Tart tomatillos, hot jalapeños, fresh lime, and sweet honey, all bound together with the creaminess of avocado, make this one a favorite sauce. Try it with any rich fish, like swordfish, salmon, mackerel, or bluefish.
Brush the tomatillos and chiles with oil and season all over with salt and pepper. Grill the tomatillos and chiles, turning, until blackened on all sides. Remove from the grill and coarsely chop the tomatillos. Stem, seed and chop the chiles.
Combine the tomatillos, chiles, lime juice, and honey in a blender and blend until smooth. With the motor running, gradually pour in the oil and blend until emulsified. Transfer to a bowl and fold in the avocados, onion, and cilantro. Season to taste with salt and pepper.
