Why does this recipe work?
To keep this recipe easy to make and budget-friendly, I’ve used fewer foreign ingredients. At the same time, I’ve mentioned the original ingredients so you can add those if you have them in hand.
We are using Thai red chili paste for this soup which will this soup some originality in its aroma. This paste has a long shelf life and many uses.
Fresh Galangal is difficult to get and pricy, so I substituted it with ginger.

I’m suggesting substitutes for ingredients as well as original ones in order to keep you well informed.
Thai curry paste: This is easily available in Asian stores or online. It is a paste made with Thai chilies, lemon grass, galangal, and Thai red chilies. Try to look for the vegan version to get a curry paste without shrimp paste. You can use this paste for my Thai red chicken curry as well as chicken satay.
Ginger or galangal: Use fresh ginger, if can find galangal, add it. Use can also use frozen galangal or dried galangal slices. Rehydrated dried galangal slices before use.
Lemongrass: I used fresh lemon grass, you can also use lemongrass paste too. If you use dry lemon grass then use extra and boil it with chicken stock and strain before adding it to the soup.
Sugar: if you have palm or coconut sugar, use that.
Mushroom: Shitake or Cremi mushrooms are the best choices, I used canned to keep it easy.
Coconut milk: If using coconut milk powder, use about 1 cup coconut milk powder mixed in 1½ cup water.

Variations:
