1. A pinch of salt makes everything better, including bitter foods.
Salty naturally counteracts bitterness, so don't use a pinch of salt in meals that are too bitter.
2. Try a little baking soda, which is very alkaline and a great way to correct excessive bitterness. Sprinkle the food slightly and mix it well to see if it helps.
Be very careful not to add too much.
3. Squeeze in some vinegar or lemon juice; these naturally sour flavors can counteract bitterness. Try squeezing some fresh lemon juice or adding a tablespoon of vinegar to the vinegar to neutralize the flavor.
