Turn your heat back on low.
Add about 3 heaping tablespoons of Thai roasted chili sauce (nam prik pao น้ำพริกเผา) to your soup and stir it in.
Also about 10 tablespoons of evaporated milk.
Mix it all in and let your soup heat up for about 1 minute.
At this stage, you’ll need to taste test and evaluate. The roasted chili sauce and creaminess from the evaporated milk will alter the flavors from the clear version, so you might need more lime juice and more fish sauce. Just keep taste testing until it’s exactly how you like it.
And there you have the creamy version of tom yum.
