Four filling names are especially useful when choosing a mooncake: lotus seed paste (莲蓉, liánróng), red bean paste (豆沙, dòushā), five-nut (五仁, wǔrén), and salted egg yolk (咸蛋黄, xián dànhuáng). They signal different flavor and texture directions, but the package label—not the name alone—defines a particular product.
For the broad beginner overview, start with What Does a Mooncake Taste Like?. The Mooncake Dessert Record holds the stable identity; this page stays focused on fillings.
Quick filling comparison
| Filling | Flavor direction | Texture | Beginner expectation |
|---|---|---|---|
| Lotus seed paste | Mild and sweet | Smooth and dense | A smooth, mild starting point |
| Red bean paste | Sweet cooked bean | Smooth or lightly textured | Familiar if you enjoy sweet adzuki desserts |
| Five-nut | Roasted; sweet, savory, or mixed | Chopped and varied | Best for people who like roasted flavor and varied texture |
| Salted egg yolk | Salty against sweeter paste | Firm to grainy | Choose it for a clear sweet-salty contrast |
What does lotus seed paste taste like?
Lotus seed paste is commonly mild, sweet, smooth, and dense. A documented preparation cooks softened lotus seeds with sugar and oil until the paste is smooth enough to hold its shape. Producers use different recipes, so the name does not guarantee one sweetness level, color, or oil content.
Lotus seed paste is a practical starting point for someone who wants a uniform texture and a gentle base. It is also often paired with salted egg yolk, which creates a clearer sweet-salty contrast.
What does red bean paste taste like?
Red bean paste has a sweet cooked-bean flavor and a dense consistency. Some versions are finely pureed; others retain more bean texture. Compared with lotus seed paste, red bean usually keeps a more recognizable ingredient character, but neither filling is universally sweeter.
Choose red bean if you already enjoy adzuki-bean buns, Chinese red bean soup, or rice-flour desserts. Check the label for the surrounding crust and any added egg or dairy rather than assuming the filling name describes the whole mooncake.
Is five-nut filling sweet or savory?
Five-nut filling can be sweet, savory, or mixed. Its most consistent feature is texture: chopped nuts and seeds create a roasted, varied bite instead of a smooth paste.
A Chinese government explanation of the cited national standard names walnut, almond, olive kernel, melon seed, and sesame as the main ingredients for the regulated Cantonese five-kernel category. The same explanation notes that regional and established formulas can differ. Some documented recipes also include cured ham or animal fat, so “five-nut” should never be treated as a vegetarian or allergen-safe guarantee.
What does salted egg yolk add?
Salted duck egg yolk adds a salty, firm-to-grainy center inside a sweeter paste. The surrounding filling still provides most of the volume, so the result is usually a contrast rather than an entirely savory mooncake.
Egg can also appear in a baked crust or glaze. Anyone avoiding egg should check the full ingredient and allergen statement, not simply choose a yolk-free filling name.
Are these fillings vegan, gluten-free, or allergen-free?
No category name supplies a categorical guarantee. A baked wrapper commonly contains wheat; a snow-skin recipe may contain milk or wheat starch; fillings may include egg, nuts, peanuts, sesame, soy, dairy, meat, or animal fat. Cross-contact and formulas also vary.
For packaged food sold in the United States, the FDA recommends reading the complete ingredient information every time. In other markets, follow the local label format and contact the producer when the information is unclear.
How to read a filling label
- Match the Chinese filling name to the front label or ingredient list.
- Read the entire ingredient list rather than relying on the product name.
- Check the allergen statement and any voluntary cross-contact warning.
- Check the date mark and package condition.
- Follow the product’s storage directions, especially for chilled fillings and snow skin.
Wrapper and region still matter after you choose a filling. Continue with the regional style comparison or the snow-skin and baked comparison.
