π₯© Meat Options

| Chicken breast | Slice thin | Leaner but can dry out β donβt overcook |
| Prawns / shrimp | Peel, devein | Add at the very end, cook 3β4 min only |
| Firm tofu | Cut into cubes | Vegetarian option β pan-fry first for better texture |
| Pork loin | Slice thin | Works well, cook like chicken |
| White fish fillet | Cut into chunks | Add near the end, gentle simmer 5 min |
π Mushroom Options
| Mushroom | Prep | Notes |
|---|---|---|
| Oyster mushrooms | Tear into strips | Classic Thai choice β silky, absorb the broth |
| Straw mushrooms | Halve if large | Traditional, hard to find fresh outside Asia |
| Shiitake | Slice | Readily available, good earthy flavor |
| Brown / cremini | Quarter or halve | Easy to find, works great |
| Enoki | Trim base, keep whole | Add at the very end, cook 2 min |
Best combo: oyster + shiitake for a mix of texture and flavor.

β οΈ Key Tips
- Donβt let the coconut milk boil hard β gentle simmer keeps it smooth
- Add lime juice off the heat or at the very end to keep the flavor bright
- Fish sauce and lime balance each other β adjust both until it tastes right
- Tom Ka is a soup, not a thick curry β it should be brothy
- The Lobo paste already has galangal, lemongrass, and chili β the fresh aromatics are bonus
π Result
- Fragrant, creamy, lightly spiced coconut broth
- Tender meat and earthy mushrooms
- Bright with lime, savory with fish sauce
- Mildly spicy β warmth without the burn
