The name comes straight from the cooking method — htoe refers to the continuous stirring and pressing the thick batter needs over the fire, an arm-tiring step the cake is named for.
Glutinous rice flour is cooked down with egg, coconut and sugar into a dense, deeply sweet, oil-glossed cake studded with raisins and cashews, then baked or steamed in trays and cut into squares. It's treated as a specialty treat rather than an everyday snack.
