This is so simple and easy to make. It is basically just cooked sweet potato, mashed, and flour added to make a dough, and then cooked on the griddle. You can add spices, or not, as you prefer. I made mine with just a little salt and some baking powder to make it fluff up a little more, and I used whole wheat flour. There are several different recipes for this on youtube, but this one is nice and short, and gives you the basic idea. Once you have it cooked, it works about like a pita bread or tortilla to use with a sandwich or other topping. When you add a dab of peanut butter and jam to a nice warm roti, it makes a delicious snack or dessert. I put mine in a plastic bag and in the fridge, and then just warm one up when I want to use it.
