Ingredients
-
- Thập Cẩm (Mixed Nuts and Meats): This is arguably the most iconic traditional filling for Bánh Nướng. It’s a complex medley offering a unique sweet-savory-umami experience. Ingredients typically include:
-
- Roasted Nuts & Seeds: Watermelon seeds, pumpkin seeds, sesame seeds, cashews, almonds.
-
- Candied Fruits/Vegetables: Candied winter melon (bí đao), candied lime or kumquat peel.
-
- Chinese Sausage (Lạp Xưởng): Adds a savory, slightly sweet, fatty element.
-
- Roasted Pork Fat (optional, traditional): Small cubes of seasoned, rendered pork fat for richness (less common in modern commercial versions).
-
- Lime Leaves (Lá Chanh): Thinly shredded Kaffir lime leaves provide a distinct, bright citrusy aroma that cuts through the richness.
-
- Rose-flavored cooking wine (Mai Quế Lộ – optional) for aroma.
-
- A binder, often made with maltose or sugar syrup.
-
- Thập Cẩm (Mixed Nuts and Meats): This is arguably the most iconic traditional filling for Bánh Nướng. It’s a complex medley offering a unique sweet-savory-umami experience. Ingredients typically include:
-
- Salted Egg Yolk (Trứng Muối): A crucial component in many Bánh Nướng and some Bánh Dẻo. The rich, savory, oily yolk provides a stark contrast to the surrounding sweet or savory filling and symbolizes the full moon. You can find versions with one (một trứng) or two (hai trứng) yolks.
-
- Lotus Seed Paste (Nhân Hạt Sen or Liên Dung): A smooth, delicate, and highly prized sweet filling made from dried lotus seeds and sugar. It has a subtle, unique floral fragrance and is considered a classic. Can be white (less sugar, more natural) or brown (caramelized sugar).
-
- Mung Bean Paste (Nhân Đậu Xanh): Another very popular sweet filling, made from hulled mung beans cooked and mashed with sugar and oil (often coconut oil or vegetable oil). It’s smooth, sweet, and versatile. Sometimes flavored with durian (sầu riêng) for a pungent twist popular among enthusiasts.
-
- Red Bean Paste (Nhân Đậu Đỏ): Similar to mung bean paste but made with red adzuki beans, offering a slightly earthier sweetness.
Modern and Fusion Fillings:
As tastes evolve, bakeries have introduced a vast range of contemporary fillings:
-
- Chocolate or Tiramisu: Catering to Western dessert preferences.
-
- Matcha Green Tea: Incorporating Japanese influences.
-
- Coffee or Cappuccino: For coffee lovers.
-
- Durian: Intensifying the traditional mung bean and durian combination.
-
- Coconut (Dừa): Often shredded coconut mixed into mung bean paste or as a standalone filling.
-
- Taro (Khoai Môn): A sweet, purple paste with a mild, nutty flavour.
-
- Fruit-Based: Fillings incorporating dried fruits, fruit jams, or even fresh fruit elements (though these have shorter shelf lives).
-
- Savory Seafood (e.g., Abalone, Scallop): Luxury, high-end savory options.
-
- Low-Sugar/Healthier Options: Using sugar substitutes or focusing on nut-and-seed-heavy fillings.
Instructions
-
- Prepare the Golden Syrup (Nước Đường): This is crucial and often made weeks or even months in advance. It involves cooking sugar, water, lemon/lime juice, and sometimes maltose syrup, then aging it to develop the right colour, consistency, and flavour. This syrup gives the crust its characteristic colour and texture.
-
- Prepare the Filling: Fillings like thập cẩm require chopping, roasting, and mixing numerous ingredients. Sweet pastes are cooked down until thick. The salted egg yolks are typically prepared by separating them, rinsing with wine (to reduce odor), and sometimes lightly steaming or baking them. The filling is then portioned and often wrapped around the yolk(s) into a tight ball.
-
- Make the Dough: The aged golden syrup is mixed with flour, oil, and sometimes an alkaline solution (like lye water, traditionally) or egg to form a soft, pliable dough. It usually needs to rest.
-
- Wrap the Filling: A portion of dough is flattened into a disc, the filling ball is placed in the center, and the dough is carefully sealed around it, ensuring no air pockets remain.
-
- Molding: The filled ball is lightly dusted with flour and pressed firmly into a decorative mooncake mold (wood or plastic). It’s then carefully demolded onto a baking sheet.
-
- Baking and Egg Wash: Baking is often done in stages. The cakes are baked briefly at a high temperature, then removed, allowed to cool slightly, and brushed with an egg wash (egg yolk mixed with water or milk). They are returned to the oven at a slightly lower temperature to finish baking and achieve the desired golden-brown, glossy finish. Sometimes a second egg wash and bake cycle is used for deeper colour.
-
- Resting: Baked mooncakes often taste better after resting for a day or two, allowing the oils from the filling to meld with the crust, making it softer and shinier (called “returning oil” – xuống dầu).
Making Bánh Dẻo (Sticky Rice Mooncakes):
-
- Prepare the Syrup: A simple sugar syrup is made by dissolving sugar in water and boiling it briefly. It needs to cool completely.
-
- Prepare the Filling: Sweet fillings like mung bean or lotus paste must be pre-cooked and cooled, as the cake itself isn’t baked. If using, yolks are prepared similarly to Bánh Nướng.
-
- Make the Dough: Roasted sticky rice flour (bột bánh dẻo) is gradually mixed into the cooled sugar syrup, often with added pomelo blossom water or vanilla extract for fragrance, and a little shortening or oil for softness. Kneading forms a soft, pliable, white dough.
-
- Wrap and Mold: The process is similar to Bánh Nướng: flatten dough, encase filling, seal well. However, the dough is much stickier. Generous dusting with dry roasted sticky rice flour is essential during wrapping and especially before pressing into the mold to prevent sticking.
-
- Demold and Serve: Carefully remove the cake from the mold. Bánh Dẻo are ready to eat immediately or within a few days; they don’t require baking or resting like Bánh Nướng.
Due to the complexity and specific ingredients (especially the aged syrup for Bánh Nướng and roasted sticky rice flour for Bánh Dẻo), many people prefer to buy mooncakes from reputable bakeries.
