Nian Gao Baked Sweet Potato Sticky Rice Cakes Food

CHINESE NEW YEAR SWEET RICE CAKE (NIAN GAO)

Steps:

• Prepare two 8-inch round baking pans by brushing the insides with vegetable oil.
• Add 2 cups of water and the ginger to a medium-sized pot, bring it a boil, then let it simmer for 10 minutes over low to medium heat with the lid covered. Turn off the heat, and stir in the brown sugar and allspice until the sugar is dissolved completely. Remove the ginger slices. Now add 1 1/2 cups of cold water to cool down the mixture so its warm, not hot.
• In a large mixing bowl, mix the two kinds of flours together and then slowly add in the sugar water mixture. Stir thoroughly until the batter is smooth (without any lumps). Now stir in the vanilla extract, molasses, orange zest, and 2 teaspoons of vegetable oil until thoroughly combined. The resulting batter should have a consistency similar to condensed milk. If the batter is too thick, add a bit more water a couple tablespoons at a time until the desired consistency is reached.
• Pour the batter evenly into two foil pans. Gently tap the pans against your countertop to get rid of air bubbles. Top each pan with three decorative dates in the center, if using. Put both pans in a double-decker bamboo steamer and steam for about 1 hour on high heat (the water should be boiling, but should NOT be bubbling high enough to touch the foil pans). You might need to add water into the steamer midway to avoid having the water dry up and burn your bamboo steamers.
• After 1 hour, poke a toothpick into the rice cake. It's done if the toothpick comes out clean--just like a regular cake! Regarding steaming techniques, for this recipe and in general, it doesn't matter what type of vessel you use. The core goal here is to use steam to cook the food, which means it's important that the steam doesn't escape.
• For example, if you use bamboo steamer, you will also need a pot that fits the bamboo steamer perfectly so there is no visible steam escaping. If you don't have a pot that fits the bamboo steamer, you will need to put the bamboo steamer inside a much larger pot with a lid and set the bamboo steamer on a rack above the water. Whatever you decide to use, with the correct set up, you should not see steam escaping!

NIAN GAO (BAKED SWEET POTATO STICKY RICE CAKES)

Steps:

• Combine the glutinous rice flour and ¾ cup/180 grams water in a bowl to form a dough. Cover tightly and refrigerate for at least 6 hours and up to 24 hours.
• Heat oven to 400 degrees. Wash and scrub the sweet potatoes and pat them dry thoroughly with a clean kitchen towel. With a fork, poke holes all over the sweet potatoes. Bake on a foil-lined pan until a fork can pierce it with no resistance, 40 to 50 minutes.
• When cool enough to handle, peel off the skin. Pass the sweet potato through a ricer or mash with a fork. Measure out 1¼ cups/320 grams of the mashed sweet potato. (Reserve any remaining for another use.)
• Heat oven to 350 degrees.
• Combine coconut milk, sugar and salt in a large saucepan. Set the saucepan over medium-low heat, and whisk until the sugar dissolves and the mixture is hot but not boiling, about 10 minutes. Remove from the heat and add the butter, stirring until it melts. Mix in the sweet potato mash, followed by the tapioca starch, then add the refrigerated wet glutinous rice flour gradually in chunks, whisking as you go. Add the egg and whisk until smooth.
• Heat 1 or more kuih bahulu pans in the oven until very hot, 7 to 8 minutes. If you don't have a kuih bahulu pan, a decorative cakelet pan or mini muffin tin made out of cast iron or aluminum works (see Tip). The batter yields 24 to 42 nian gao, depending on the size of the hollows; work in batches if needed (see Tip). Remove the pan from the oven and, using a silicone or pastry brush, lightly and quickly brush its hollows with oil. Stir batter, then quickly pour it into the hollows, filling them 80 to 90 percent full.
• Bake on the center rack until golden brown on top and a toothpick inserted into the center of one emerges moist and sticky, but with no pasty raw batter on it, 20 to 40 minutes. The exact baking time will vary depending on the size and heft of your pan.
• Use a wooden skewer or butter knife to pry out and remove the nian gao from the pan. If the pan was properly heated and oiled, the nian gao will not stick. If needed, repeat with the remaining batter. If the pan cools off too much while you are removing a batch of nian gao, heat it for a couple of minutes in the oven before baking the next batch.
• These nian gao are best served slightly warm while the edges are still crisp and the centres are soft and chewy. They are best the same day they are made. You can keep leftovers in a covered container in the refrigerator and steam, pan-fry or microwave them to reheat the next day, but they will not completely recover their freshly cooked texture.
