fa ("sky pointing chili") is slightly less spicy than the smaller chilies. The very large phrik yuak, which is pale green in color, is the least spicy and used more as a vegetable. Lastly, the dried chilies: phrik haeng are spicier than the two largest chilies and dried to a dark red color. Other typical ingredients are the several types of eggplant (makhuea) used in Thai cuisine, such as the pea-sized makhuea phuang and the egg-sized makhuea suai, often also eaten raw. Although broccoli is often used in Asian restaurants in the west in phat phak ruam (stir fried mixed vegetables) and rat na (rice noodles served in gravy), it was never used in any traditional Thai food in Thailand and was rarely seen in Thailand. Usually in Thailand, khana is used, for which broccoli is a substitute. Other vegetables which are often eaten in Thailand are thua fak yao (yardlong beans), thua ngok (bean sprouts), no mai (bamboo shoots), tomatoes, cucumbers, phak tam lueng (Coccinia grandis), phak kha na (Chinese kale), phak kwangtung (choy sum), sweet potatoes (both the tuber and leaves), a few types of squash, phak krathin (Leucaena leucocephala), sato (Parkia speciosa), tua phū (winged beans) and khaophot (corn). Among the green, leafy vegetables and herbs that are usually eaten raw in a meal or as a side dish in Thailand, the most important are: phak bung (morning glory), horapha (Thai basil), bai bua bok (Asian pennywort), phak kachet (water mimosa), phak kat khao (Chinese cabbage), phak phai (praew leaves), phak kayang (rice paddy herb), phak chi farang (culantro), phak tiu (Cratoxylum formosum), phak "phaai" (yellow burr head) and kalamplī (cabbage). Some of these leaves are highly perishable and must be used within a couple of days. Several types of mushroom (het) also feature in Thai cuisine such as straw mushrooms (het fang), shiitake (het hom), and white jelly fungus (het hu nu khao). Flowers are also commonly used ingredients in many Thai dishes, either as a vegetable, such as dok khae (Sesbania grandiflora) and huapli (the flower bud of the banana), or as a food coloring, such as with the blue-colored dok anchan (the flowers of the Clitoria ternatea, which can also be eaten raw or fried). Fruits Fresh fruit forms a large part of the Thai diet, and are customarily served after a meal as dessert. The Scottish author John Crawfurd, sent on an embassy
