1 - If you are searching for milder chiles, always select ones that have broad shoulders and blunt tips. For hotter chile peppers, select chiles with pointed tips and narrow shoulders. This is important because you can have up to 35 different piquancies on one plant at a time.
2 - The chemical that makes peppers hot, is capsaicin,an oil and will stick to your skin. It is typically best to wear rubber gloves when working with chili peppers if your skin is sensitive. Also, avoid rubbing your eyes or other sensitive areas of your body after handing hot peppers. It doesn’t feel good to get a blast in the eye…or anywhere else tender. Believe me, I’ve heard stories.
