See first :
A recipe gives quantities, but your salt is not the same, your tomatoes are not the same, and your stock cube is not either. The only way to know if it is good is to taste, with a clean spoon, every time you add something and above all at the end. Adjusting is correcting by small touches, and tasting again.
Taste before serving, always. If it is flat, it is almost always salt or acidity that is missing, not one more spice.
Ten seconds each time. It is the difference between a decent dish and a dish people ask you the recipe for.
You corrected in the wrong direction, too much lemon for example: a pinch of sugar brings the balance back. You cannot tell what is missing any more: add a pinch of salt and a few drops of lemon, one of the two will wake the dish up.
Basque-style chicken. Taste the sauce after simmering: depending on the tomatoes, it will need a pinch of salt or a pinch of sugar, and you will know right away.
