RE: Dominican Republic
It's a beautiful country, with lovely people. The cuisine is not spicy hot at all. You can do a google search for the recipes for the following (sorry, just know that I loved eating these dishes in Santo Domingo, and in Dominican restaurants in New York).
1) Mofongo-a delicious dish of mashed plantains (I think they are peeled and boiled like potatoes beforehand), with pork cracklings (optional) and covered in red onions fried until soft in olive oil.
2) Sancocho- a tasty chicken soup, containing yucca.
3) fried yucca (a starchy tuber- fried up like thick steak fries- I find it has a subtly sweet taste like yams, which I believe it is "related" to botanically).
4) And, of course, arroz con habichuelas (rice and pigeon peas) a traditional accompaniment to just about any dish.
Sorry about the lack of recipes, but again, they are pretty simple in concept, and I am sure the internet would yield simple recipes for each one.
