I find the concept of stepping back from the problem to reflect helpful when trying to attain the right flavor profile of a vinaigrette for example. When students combine vinegar, mustard, garlic, oil, salt and pepper and begin tasting for a balanced flavor, the subtle balance needed can be difficult to achieve after four or five tastings if the viaigrette is too sharp, too hot or too salty. I them tell it is important to step back, give their taste buds a break and evaluate/reflect on what is known and possible soultions. Their thought process(and taste buds) can become more clear and help them make viable choices to solve the imbalance.
