Pour milk into a large bowl, add yeast and mix, and set aside for 5 minutes or until it rises; you can also use water instead of milk. If using instant yeast, skip the proofing.
2 cups warm milk or water, 2½ tsp. yeast
Then add butter or margarine, sugar, egg, salt and nutmeg, and mix until all the ingredients are thoroughly combined.
¼ cup melted butter or margarine, 1 large egg, ½ cup sugar, 1 tsp. salt, 1 tsp. nutmeg
Add flour and mix using a wooden spatula. Then use an electric mixer until the dough leaves the sides of the bowl and comes to the center, gradually add more flour while mixing.
4 cups All-purpose flour (plus 1 Cup for dusting)
Cover the dough with plastic wrap and a clean kitchen towel, and leave for 1 hour warmly until it rises.
When the dough is ready, take a golf-ball size portion of it and fold it so that one side is rough and the other is round and smooth, arranged on a tray.
Pour oil into a pot over medium heat. When oil is hot enough, when you drop a portion of dough in the oil, it takes time to get golden brown, which means the temperature is ideal for frying.
When gateau is ready, take out of oil and place it on a plate lined with absorbent paper.

Notes
Mix yeast with lukewarm water/milk to efficiently activate it. If water is very hot, it will kill the yeast; if it is very cold, the yeast won't activate.
Let it proof in a warm area; otherwise, it won't double in size.
Don’t over-knead. Knead until the dough is smooth and elastic. Over-kneading can make the buns dense.
Heat the oil to about 350°F (175°C). Test the temperature by dropping a small piece of dough in; it should sizzle and rise to the surface. Fry in small batches to prevent the oil temperature from dropping, which can lead to greasy buns.
Use a slotted spoon to remove the buns and drain excess oil on paper towels to keep them from becoming greasy.
