When zesting spicy peppers, always wear gloves to protect your skin from capsaicin, the compound that causes the burning sensation. Avoid touching your face, especially your eyes, until you've thoroughly washed your hands and any utensils used.
Spicy peppers contain capsaicin, an irritant that can cause a burning sensation and skin irritation. Zesting peppers releases this compound, making it easily transferable to your hands and other surfaces. Wearing gloves creates a barrier, preventing the capsaicin from coming into direct contact with your skin. After handling the peppers, even with gloves, it's crucial to wash your hands thoroughly with soap and water. Also, clean any surfaces or utensils that came into contact with the peppers to avoid accidental contamination. If you experience burning or irritation, washing the affected area with soap and water can help alleviate the discomfort. Milk can also help neutralize capsaicin due to its fat content.
If you don't have gloves, you can try rubbing your hands with vegetable oil before handling the peppers. The oil will create a barrier, making it easier to wash off the capsaicin afterward. However, gloves are still the most effective method.
