Combine all ingredients for dough except hot water and mix well. Slowly add hot water and keep mixing with a spatula. It should look really wet. Cover and set aside for 1 to 2 hours.
Mix dough again with a spatula. Dough should be more formed now.
Brush a thin layer of oil on a cookie sheet. Heat frying oil to 350°F over high heat.
Meanwhile, divide dough into 14-16 little doughnuts. Roll them with the palms of your hands and place on oiled cookie sheet.
Place doughnuts one by one into hot oil, about 4-6 at a time. They will increase in size, so do not crowd pot. As soon as doughs puffed up, turn off heat and keep frying until fully cooked and golden, about 3-4 minutes. Continue to rotate evenly in oil to ensure even cooking.
Remove from pan, drain excess oil and roll in sugar. Repeat with remaining ingredients. Enjoy!
