Red chilli is the spice in curry that usually has tongues tingling. It should be used in moderation to add a natural red glow to the dish together with a sharp spicy flavour without setting the mouth on fire. Red chilli powder works well in a marinade to give a natural red colour if you do not want to use food colouring. It is one of the key ingredients when making a traditional Punjabi masala sauce and usually added with the turmeric once the tomato has been added. Red chilli is known to be a good source of vitamin C and been proven to soothe a cold and clear congestion of a blocked nose. Research suggests it helps burn calories and aids in weight loss.
