This Thai sweet and sour dish differs from the Chinese variety in that the sauce has no starch thus the dish is much lighter and more delicate. It also does not have tomato ketchup in it.
 Thai cooking can sometimes prove difficult due to the fact that Thai ingredients vary in taste and intensity. One bottle of fish sauce tastes different to another and may also be saltier. So, when cooking Thai food, you have to taste your food as you cook, season it bit by bit and correct the taste as you go along.
