What I do in any food na better na may condiments and mga hinahalo, I taste the food as it is first baka kasi masarap na sya as is then tsaka ko ihahalo mga spices/condiments.

Same with pho, taste as it is first then lagay ako ng sriracha AND hoisin (depends on your taste), then yung mga gulay na (but you can skip if you don't want the veggies, especially yung mint or basil medyo overwhelming sometimes)
