Place the poblanos directly on a gas burner on the stovetop over medium heat using metal tongs. Allow the poblanos to roast and blister for about 3-4 minutes. (If you do not have a gas stove, broil the peppers on high in the oven on the highest rack for 4-6 minutes per side or until they are blistered.)
2 poblano peppers
Flip the poblanos and repeat on the other side. Rotate if needed to blister the whole surface of the pepper.
Place the charred peppers in a glass bowl. Cover tightly with plastic wrap. Allow the peppers to rest for 10-15 minutes.
Once the peppers have rested, remove them from the bowl and place them on a cutting board or plate. Using your hands and a paper towel peel and remove the skin, stem, and seeds.
Rinse the peppers to remove any excess skin and seeds. Place on a paper towel and pat dry.
Pulse the poblanos, cilantro, garlic, lime, onion powder, dill, cumin, and salt.
1/2 cup cilantro leaves and stems, packed, 3 cloves garlic, 1/2 lime, juiced, 1 1/2 teaspoons onion powder, 1/2 teaspoon dried dill weed & cumin, 1/4 teaspoon Morton kosher salt*
Add the sour cream and pulse until smooth. Add more salt and lime to taste if needed.
1 cup sour cream or Greek yogurt
