This recipe makes about 12-13 small mooncakes (using a 50-gram mold).
Part 1: Understanding the Components
A mooncake has two main parts:
1. The Skin (Dough): A soft, pliable dough made with golden syrup.
2. The Filling: Traditionally, a sweet, dense paste like lotus seed or red bean, surrounding a salted egg yolk.
Key Special Ingredients:
- Golden Syrup: The key to the soft, dark skin. Do not substitute with corn syrup or honey.
- Lye Water: An alkaline solution that helps with browning and gives the skin its distinct texture. It's often sold alongside the syrup.
- Mooncake Mold: You can find plastic push-style molds online in various sizes (50g, 63g, 75g, 100g are common).
Part 2: Ingredients
A. For the Mooncake Dough:
- Golden Syrup: 85g
- Lye Water: 2g (about 1/4 tsp)
- Vegetable Oil (or peanut oil): 30g
- All-Purpose Flour: 120-125g
B. For the Filling:
- Lotus Seed Paste (or Red Bean Paste): 400-450g
- Salted Duck Egg Yolks: 6-12 (optional)
- Egg Yolk (for egg wash): 1, mixed with 1 tbsp of milk or water
Filling Ratio (Crucial!):
For a 50-gram mold, the classic ratio is 2:3 (Skin : Filling).
- Skin: 20 grams per mooncake
- Filling: 30 grams per mooncake (this weight includes the paste + egg yolk if using)
Part 3: Step-by-Step Instructions
Step 1: Prepare the Dough (A Day Ahead is Best!)
1. Mix Wet Ingredients: In a bowl, whisk together the golden syrup, lye water, and oil until well combined and slightly thickened.
2. Incorporate Flour: Sift the flour into the wet ingredients. Use a spatula to mix until a shaggy dough forms.
3. Knead Gently: Lightly knead the dough in the bowl until no dry flour remains. Do not over-knead. The dough will be soft and slightly sticky.
4. Rest the Dough: Cover the dough tightly with plastic wrap and let it rest at room temperature for at least 1 hour, or up to 4 hours. Resting allows the gluten to relax and the dough to absorb the liquids, making it easier to handle.
Step 2: Prepare the Filling
1. Prepare Egg Yolks (if using): If using salted egg yolks, steam them for 10 minutes or bake at 175°C (350°F) for 10 minutes until slightly oily. Let them cool completely.
2. Weigh the Filling: Weigh your lotus seed paste. If using a yolk, weigh the yolk and enough paste so that the total weight is 30g. For example, if a yolk is 10g, use 20g of paste. Wrap the paste completely around the yolk to form a smooth ball.
Step 3: Assemble the Mooncakes
1. Weigh Everything: Divide the dough into 20g portions and the filling into 30g portions. Keep them covered to prevent drying.
2. Flatten the Dough: Take a dough ball and flatten it into a thin, wide disc (about 3-4 inches in diameter) in the palm of your hand. The edges should be thinner than the center.
3. Wrap the Filling: Place a filling ball in the center. Gently push the dough up and over the filling, using your thumb to slowly stretch the dough.
4. Seal it: Pinch the edges together at the top to seal completely. Roll it gently between your palms to form a smooth ball.
Step 4: Shape with the Mold
1. Dust the Mold: Lightly dust the inside of your mooncake mold with flour and tap out the excess.
2. Press to Shape: Place the wrapped ball into the mold, seam-side up. Gently press down the plunger to compact the mooncake.
3. Release: Lift the mold and press the plunger down firmly to release the mooncake onto a baking tray lined with parchment paper. Space them about 1 inch apart.
Step 5: Bake the Mooncakes
1. Preheat Oven: Preheat your oven to 180°C (350°F).
2. First Bake (5 minutes): Bake the mooncakes for about 5-7 minutes until the edges start to look set. This step is to set the shape.
3. Cool Slightly & Egg Wash: Remove the tray from the oven and let the mooncakes cool for 10-15 minutes. This is crucial to prevent the egg wash from ruining the design.
- Lightly brush the mooncakes with the egg yolk wash. Use a light hand—too much wash will obscure the pattern.
4. Second Bake (10-12 minutes): Return the mooncakes to the oven and bake for another 10-12 minutes, or until the tops are golden brown and the patterns are clearly defined.
Step 6: The MOST IMPORTANT Step - "Resting"
1. Cool Completely: Let the mooncakes cool completely on a wire rack.
2. Store to Soften: Place them in an airtight container at room temperature. The skins will be hard and matte straight out of the oven.
3. Wait 1-3 Days: Over the next 1-3 days, the oil from the filling will slowly migrate into the skin, making it soft, shiny, and tender. This process is called "Resting" and is what gives mooncakes their signature texture. They are best eaten after this resting period!
Part 4: Pro Tips & Troubleshooting
- Cracking during baking? The dough might be too dry, or you may have over-kneaded it. Ensure your dough is well-rested and pliable.
- Pattern not clear? You might have used too much egg wash, or the dough was too sticky (not enough flour in the mold). The first bake might have been too long.
- Sticking to the mold? Always dust the mold lightly with flour before each press.
- No Lye Water? You can make a substitute by mixing 1 part baking soda with 3 parts water and baking it in the oven to create a concentrated alkaline solution, but it's easier to buy the real thing.
Enjoy the process and the delicious results! Happy Mid-Autumn Festival! 🥮
