Sift together whole wheat flour and rice flour and salt in a bowl. Rub in 2 tablespoons of ghee or oil.
Add rest of ingredients except oil (for frying). Gently add water to make a soft dough. Knead well until no longer sticky. Shape dough into 8 small balls.
On floured surface, roll out each ball into a 6-inch (15cm) round. Heat a griddle, place the round dough in it and dry roast.
When little brown appears on the underside, turn the roti over. Smear a little ghee or oil over the surface and drizzle 1 teaspoon ghee or oil around the roti.
Cook until both sides are golden brown. Repeat with the remaining dough.
