Bring 2-cups of water to a boil in a heavy-bottomed 1-qt. saucepan. Add rice, scallions, garlic and thyme; return to boil, then reduce heat, cover and simmer about 40 minutes or until water is absorbed and rice is tender.Remove from heat and stir in corn, breadcrumbs, salt and pepper. Let stand for about 5 minutes to cool slightly. Meanwhile, beat eggs in a large bowl; stir in the rice mixture and mash until with a fork or a potato masher until the mixture is well-blended and holding together. Form the mixture into eight patties. Heat half the oil in a skillet, preferably cast-iron. When hot, place 4 rice patties into the skillet and cook until brown and crisp, about 3 minutes. Turn carefully and cook the second side. Remove from the pan and keep warm while cooking the rest of the patties in the remaining olive oil. Serve patties topped with salsa.
