Easy Gratineed Eggplant

It’s finally starting to feel like summer so today I’m making a dish that has summer written all over it.
A super simple Gratineed Eggplant — a dish that get raves from anyone who's tried it.
I know that “gratineed” sounds like a fancy word but in reality it just means to bake or broil in au gratin style. That’s it.

Mom's Pink Lemonade

When I was a kid I was 100% convinced that pink lemonade was made from pink lemons (yes, pink lemons do exist but unfortunately their light pink flesh juices run clear).
Then for years I thought it was made by adding pink grapefruit juice to lemonade; it’s not.
Pink lemonade is a popular cloudy variation of traditional lemonade made with added grape juice or cranberry juice, giving the drink its distinctive pink color.
If the taste of pink and traditional are exactly the same, why does the former is more popular than the latter?
