The intensity of their flavor ranges from mild to extremely hot. Generally, intensity of the heat in the taste of the pepper decreases as the size of the pepper increases. Thus, the larger peppers are most often mild, while the smaller peppers are spicy and hot. The fiery burning sensation present in some peppers is due to the natural substance called capsaicin that produces the hot taste in the mouth. Capsaicin is present in the inner white ribs (pith) running down the middle and sides of the pepper. Removal of the ribs, as well as the seeds that rub against the ribs and absorb the spicy capsaicin, will reduce the hot intensity of the pepper. Another alternative to counteract the hot taste is to use milk, yogurt, bread, or rice to absorb the intensity of the capsaicin. In dairy products, the substance casein exists which assists to break down the heat effects of capsaicin.
Peppers are available in various colors such as red, green, orange, yellow, white, and black. When selecting peppers, choose any that do not have a wrinkled or dull colored outer flesh. When preparing hot peppers, use caution not to touch the eyes or similar areas that can be painfully affected by the capsaicin that rubs off on hands. To assist in removing capsaicin from hands, use dairy products such as yogurt or ice cream, rubbing the product over the areas affected. Also, another alternative is to use a combination of cooking oil, such as olive oil, and dish detergent to create a wash that will reduce the effects of the capsaicin residue.
