Green Curry. Considered to be the spiciest curry in Thailand, it is also sweet thanks to the high amount of coconut milk that is added to the dish. The base is made with fresh, young green chilis which makes green curry hotter than other curries and in our opinion one of the best tasting! While still spicy and a bit sweet, this plays to your savory taste buds more than green curry. The color comes from the bigger red chilies used to create the base. The chilies are crushed with garlic, lemongrass, shallots, ginger and fish paste and added to coconut milk. Red curry is spicier and less rich than yellow curry. The yellow curry base is made of plenty of tumeric, cumin yellow mustard seed, nutmeg, kaffir lime leaves and juice.
