Grown primarily in Thailand, this pepper can also be found in parts of Mexico and the United States. Thai peppers are small and slender with a very pointed end, but do not let its non-threatening size be deceiving. This blazing hot pepper has a seriously strong lingering heat. Often used in curries and soups, this pepper can also be added sparingly to salads and stir-fries. Mix with sugar and salt for a unique condiment that will enhance any fresh fruit.
