Is there a way to remedy a dish that is too acidic?
Sometimes a bit of water can remedy the situation.
Or add oil to round out the flavors. Creams, cheese, milk can also soften the too acidic dish/dressing, etc.
What type of dish is it? What other ingredients are involved? Thank you. ;o)
For tomato-based dishes a pinch of sugar may help (most Italians use a pinch of sugar in all of their tomato sauces to balance the acidity). And by a pinch, I mean literally, a pinch. Less than 1/4 teaspoon. Start small, taste, taste, taste, and see what it takes to get your dish to where you want it,
