Why it happens

Main causes

  • Overripe or tough raw ingredients
    Older or overripe eggplants naturally contain more bitterness, which may not be fully balanced by the recipe.
  • Overcooking or overheating
    Prolonged cooking or excessive frying can create a strong bitter taste instead of mild richness.
  • Insufficient pre-treatment
    Soaking or salting eggplants before cooking is often necessary to reduce natural bitterness.
What to do

Next steps

  1. 1

    Determine if the bitterness is safe

    If the smell is normal and there are no signs of fermentation, the issue is likely taste-related rather than spoilage.

    Important
  2. 2

    Balance the flavor when serving

    Sweet or acidic ingredients can help reduce the perception of bitterness.

  3. 3

    Adjust the process for the next batch

    Use younger eggplants and include proper soaking or salting steps before cooking.
