Thai Yellow Curry - a lot milder than the green or red curry - the ingredient that gives any Thai curry variety the characteristic yellow hue is of course the classic and amazing turmeric.  Thai yellow curry combines a whole range of fragrant, fresh herbs and dried spices. There is not much chilli added to a yellow Thai curry hence the mildness. Thai green curry - well, if you can handle some heat, then a green curry is the one to go for. It contains incredibly aromatic fresh ingredients like fresh green chillies, lime, coriander, kaffir, and Thai basil, This version is a super delicious Thai curry dish no matter what. The coconut milk comes in for flavour and depth but also to tone down the spiciness level. Green curries are usually the spiciest of all three colour Thai curries. Thai red curries - are generally milder than the green and a little spicier than the yellow. The red colour in this Thai curry is given by the chillies in the paste. The fiery heat given by the chillies is again toned down by coconut milk. It can also be toned down by removing the seeds and the inner whitish nervures from the chillies and that will create a milder curry paste. Also, the type of chillies you chose will make a difference in the level of spiciness.
