Poblano peppers are larger, darker green and milder than jalapenos, but they can still burn the mouth and skin. This is caused by an oil in the pepper known as capsaicin. It's best to try to prevent burns resulting from preparing and eating poblano peppers if at all possible, but should they happen, remedies are available.
Preventing Poblano Skin Burns
Prevention is the best way to stop poblano pepper burns. Put disposable gloves on before cutting, washing or handling poblanos. When cutting peppers, avoid touching your face with your hands. If grinding dried poblano peppers, consider wearing goggles to prevent the dust from getting into your eyes.
Cure Pepper Burns on the Skin
Cover burned skin with vegetable oil. Keep the oil over the burn until the stinging subsides. Wash the oil from the skin with soap and water. If that does not work, soak the burned skin with milk or cream. Follow by washing the skin thoroughly with soap and water.
Poblano Pepper Mouth Burn Remedy
Water will not soothe a poblano pepper burn in the mouth. Slowly drink milk or eat ice cream or yogurt. Eat some form of starch--bread and rice are good choices. Starches will help to soak up some of the capsaicin oil from the mouth. Acidic liquids such as tomato juice and fresh lemon and lime juices will balance out the alkalinity of the capsaicin from the poblano pepper and soothe the burn.
