Prepare the broth. See attached pic for broth. Chicken need to be fully covered in water. Cover & let boil. Once boil, removed lid let boil for 5-10mins. Turn heat to the mid lower setting & simmer for 25mins with lid on. Remove chicken from the pot & let dry. Prepare ingredients. See pic. Use pure coconut milk. See pic. Many brands add xanthan gum, thickener & many "non-coconut" extras in their canned coconut milk. Read label before buying canned coconut milk.

Blend ingredients in B with a bit of water until smooth & pasty. Prepare ingredients in C with enough water to make a smooth curry paste. Heat wok/big pot with 1/2 cup of cooking oil. Add blended spices & sauté until translucent & aromatic. Add in curry paste. Keep stirring until aromatic for 5mins or more.

Next, add chicken broth to the wok/big pot. Stir or whisk to combine. Let boil. Meanwhile, prepare accompaniments - blanch fishball/fishcake & yellow noodles or soften Vermicilli. Next, pour coconut milk into the wok/big pot of boiling broth. (Note: shake or whisk coconut milk in separate bowl as it curdle sometimes). Stir curried broth to mix. Taste & adjust seasoning accordingly. It should be lightly strong as blanched noodle/vermicelli is tasteless. Simmer until it bubbles then Turn off heat.

Order to assemble - noodles/vermicelli, curried broth, chopped chicken, fish ball/fish cake, bean sprout. Serve hot. Assemble only before serving. Reheat curried broth (if necessary) just before serving. When reheating curried broth, turn off heat immediately right after broth just bubbled or boiled. Do not leave broth boiling too long as it has coconut milk that would turn oily when left boiling longer than necessary.
