Common Mistakes to Avoid
Making the perfect Slow Cooker Tom Kha Soup is easy, but there are common pitfalls to watch out for.

- Not adjusting seasoning: Each ingredient can vary in strength. Taste your soup before serving and adjust fish sauce, lime juice, and brown sugar as needed for balance.
- Overcooking the vegetables: Adding mushrooms too early can cause them to become mushy. Stir them in during the last cooking stages for the best texture.
- Ignoring liquid ratios: Too much or too little broth can affect consistency. Stick to the recipe measurements to achieve that creamy soup base.
- Serving without garnishes: Fresh cilantro and green onions elevate the dish. Don’t forget this final touch for added freshness and presentation.
