Bitter Japanese eggplants

Hm, you could rough chop them, and douse with a sauce of soy, rice vinegar (or balsamic), sugar, ginger, and chili oil if you have those in your pantry. Or maybe try to doll them up as baba ghanoush by blending the flesh with a scoop of tahini, olive oil, and lemon juice? (I'd skip the garlic since they're already bitter.) If you have roasted red peppers, you could chop some up and put them on the baba to add a little more sweetness. Hope that helps!
