Add enough oil to large cast iron skillet, to reach halfway up the sides of the skillet. Heat oil over medium-high heat.
Meanwhile, in a mixing bowl, combine cornmeal (2 cups), salt (1 1/2 teaspoons), sugar (1 teaspoon), green onions (1/4 cup), and thyme (2 teaspoons). Add the boiling water a little bit at a time. You only want to add enough to create a dough. Stir until smooth. Allow the batter to rest for 10 minutes before scooping.
Scoop or spoon the batter into large tablespoonfuls and gently flatten with wet hands. When the oil is hot (375ºF (190ºC)) fry in batches, turning once until crisp and golden brown, about 5 minutes. Drain on paper towels. Serve
