There's some reality to the limited palate, but I believe it is more limited to ability to buy more expensive items and the limited availability in the stores.
While we all have our native comfort foods, those Dominicans who can afford enjoy a wide variety of foods.
As for my experience (not all southern dishes), my Dominican friends seem to enjoy whenever I cook...
- meatloaf
- chicken pot pie
- brocolli casserole
- shrimp po boys
- blueberry pie
- chili con carne
- baked beans
Banana pudding with nilla wafers is always a hit here in DR.
Southern style fresh creamed corn has been hit & miss. Some love it, others can't figure out why it's cut off the cob.
Not every story is a success, though. Several years ago when I was living in Alabama, I took a visiting Dominican friend to Cracker Barrel. He wasn't able to enjoy his food as he spent the bulk of his time trying to figure out who around him were members of the KKK.
