Tip: In a large bowl add water and a teaspoon of salt. Toss in the diced Eggplants and leave in for about 15 minutes. (see photo) This step is necessary because Eggplants tend to bitter, and this is a good way to get rid of the bitterness. Place pan into your oven and bake at 180 degrees for 1 hr. Check your food while it is baking, and toss it around a few times, so that it does not stick to the bottom.
