These distinctive white noodles are almost spaghetti like. They are made from rice flour
In the above picture you can see the sauces for three soups that go with khanom jeen noodles. The larger one on the right is "nam ya ga ti" which is sometimes shortened to just "nam yaa". It is the famous version for the central region. In the top left is "nam ya ba" and bottom left is "nam ngiaw". The missing soup is "nam prik". The first two I mentioned have fish balls (look chin pla) but nam ngiaw is served with chicken pieces.
ขนมจีน น้ำยา - khanom jeen nam yaa
The fish curry sauce is made with fish, ginger, garlic, shrimp paste, shallots, galangal, lemon grass, peppers, coconut milk and fish sauce.
ขนมจีน น้ำเงี๊ยว - khanom jeen nam ngiaw
This curry is made with garlic, red curry paste, yellow bean sauce, diced tomatoes, turmeric, fish sauce, spring onion and coriander. You can use either chicken (as in the picture) or pork ribs.
The sauce is poured on top of the noodles. You then have a selection of vegetables which you eat with it. These include: basil, quail eggs, pickled mustard greens, shredded cabbage and beansprouts.
