Eggplants can tend to be bigger if undercooked, so cooking them properly is key! Because they're mostly made up of water, which is about 80% of what makes an eggplant, making sure it evaporates during the cooking process will be the number one secret to a good cooking method. I prefer to roast in a high heat oven, while turning them every 15-20 minutes to ensure they're roasting properly. The end result should be a smooth textured eggplant!
