We love the convenience of making this in the oven, rain or shine. Simply place the peppers with the stems on, on a baking sheet and place under the broiler. Char peppers until you see blistered skin-about 5-6 minutes flipping once. Then steam by covering with plastic wrap and peel the skin off.
You can likewise char the skin on the stove in a heavy duty saucepan or over direct gas flame.
Combine roasted poblanos, scallions, cilantro, lime juice, sour cream and seasoning. Blend until smooth in a blender or food processor. If you want to stir in extra sour cream or broth until smooth and velvety. Add melted cheese or Queso and blend in.
Adjust Consistency
Add broth or olive oil for a thinner sauce. Also keep it as chunky or smooth as you prefer. Transfer to a bowl and use right away.
Roasting breaks down vegetal compounds and develops smoky flavors that define the sauce. Raw poblanos taste grassy, while roasted poblanos become sweet and smoky.
Why Blending Matters
Blending emulsifies fats and liquids, creating a stable, creamy sauce without separation.
Why Dairy Works So Well
Fat from the sour cream binds with roasted pepper compounds, smoothing bitterness, spice and enhances sweetness.
