Peel the prawns. Place heads and shell in pot, reserve meat.

Use a meat mallet or similar to bash the garlic, chilli and lemongrass so they burst open to release flavour. Add into pot.

Crush kaffir lime leaves with your hands. Add into pot.

Add galangal, stock and water. Bring to simmer on high heat, cover, then reduce to medium and simmer for 10 minutes.

Strain the broth, discard the prawn shells etc, then return broth into same pot over low heat.

Add onions and mushrooms, simmer 3 minutes. Add tomatoes, simmer for 1 minute.

Add prawns, simmer 2 minutes or until just cooked.

Stir in sugar and fish sauce, simmer for 1 minute.

Add lime juice, then taste. Adjust sweet (sugar), salt (fish sauce) and sour (lime) to your taste (trust me, you'll know when you like it!).

Ladle into bowls and serve with fresh coriander and fresh chilli! This is the CLEAR version of Tom Yum.

When you add sugar, also add Thai Chilli Paste and evaporated milk.

Then continue with recipe!
