Nian gao is a sticky rice cake. 年 (nian) means “year” and 糕 (gao) means “cake,” but nian gao can also mean “sticky cake” or “higher year,” because the pronunciations have double meanings. The cake can be steamed and served as is or cut into slices and pan-fried after steaming.
New Year's cake (nian gao)
In a small bowl, soak the red dates in cold water until softened, about 30 minutes. When softened, remove and discard the pits.
Meanwhile, cut each candy slab into 8 pieces. Place the candy in a heatproof bowl and pour 2 cups boiling water over the candy. Set aside until the candy is dissolved and completely cooled.
Grease a heatproof, 8-inch-round, 3- to 4-inch-deep soufflé dish or other straight-sided bowl, using 2 teaspoons vegetable oil.
Place the rice flour in a large bowl. Make a well and stir in the cooled sugar water. Knead the mixture until a dough forms in the bowl, adding an additional 1/3 cup cold water until the dough is smooth, slightly moist and shiny, 5 to 10 minutes.
Place the dough into the prepared dish and pat until it fills the dish evenly and the top is level.
Halve the red dates and place, cut-side down, in a ring around the outside of the dough, leaving a few to decorate the center.
Sprinkle the top with sesame seeds. Coat with the remaining 1 teaspoon oil, using your fingers and lightly pressing down on the dates and sesame seeds.
In a covered steamer large enough to fit the dish without touching the sides of the steamer, bring water to a boil over high heat. Carefully place the dish in the steamer, cover, and steam until the cake begins to pull away from the sides of the pan, 35 to 45 minutes. Check the water level occasionally and replenish, as needed, with boiling water.
Carefully remove the dish from the steamer and pour off any excess liquid on the surface. Place on a rack to cool. Loosely cover and set at room temperature in a cool room until the next day, when it will be ready to eat.
Run a knife along the edge of the cake to loosen the sides. Place a cake rack over the bowl and invert to unmold. Flip the cake right-side up on a cutting board. Wrap the cake in plastic and refrigerate until ready to use.
When ready to eat, cut the cake into quarters. Cut each quarter crosswise into two (2-inch-wide) strips. Cut each strip crosswise into scant 1/4-inch-thick slices. Beat the egg in a small bowl, until frothy. Dip the slices in the egg.
Heat a flat-bottomed wok or skillet over medium heat until hot but not smoking. Add just enough vegetable oil to barely coat the wok. Pan fry the egg-dipped slices in batches until golden brown, 2 to 3 minutes on each side. Serve immediately.
