Cooking encyclopedia Habits worth keeping
A dish that tastes flat usually needs acid or salt, not more of the main flavour.
Taste, then ask which of five things is missing: salt, acid, fat, sweetness, heat. Add one at a time, in small amounts, and taste again.
Flatness is rarely a shortage of the headline ingredient. Salt makes everything else legible; acid lifts and separates; fat carries aroma and lengthens the finish; a little sweetness softens harsh edges; heat and bitterness add structure. More tomato in a flat tomato sauce usually makes it flatter and larger.
The last two minutes of anything.
Adding more of the main ingredient; correcting with several things at once so you cannot tell what worked; tasting only once, at the end, when it is too late to fix.
