1. Stir-frying: Use high heat to quickly evaporate the moisture in the bitter gourd, reducing its bitterness.
2. Salting: After cutting the bitter gourd, sprinkle a little salt on it to draw out the moisture. Squeeze it dry before cooking, which is also an effective way to reduce bitterness.
3. Icing: Soak the sliced bitter gourd in ice water for a while before eating, and the bitterness will be less.
4. Blanching: Briefly blanch the sliced bitter gourd in boiling water before stir-frying, which can also reduce the bitterness.
