As autumn approaches and the moon glows full and bright, families across China gather to share a sweet treat that has captivated hearts and taste buds for centuries: the mooncake. These round, golden pastries are at the heart of the Mid-Autumn Festival, a time of reunion, gratitude, and well-wishes. But what’s inside these iconic cakes? Let’s discover the fascinating array of fillings that make China’s mooncakes so irresistible.

The Origins and Symbolism of Mooncakes

A Bite of History

Mooncakes date back over a thousand years, with roots often linked to the Tang and Song dynasties. By the time of the Ming dynasty, the custom of eating mooncakes during the Mid-Autumn Festival was already widespread. Over time, regional bakers began filling mooncakes with local specialties, blending tradition with innovation.

Symbolic Meanings

The shape and filling of a mooncake are steeped in symbolism. Their roundness represents unity, harmony, and the full moon—a symbol of reunion in Chinese culture. Sharing mooncakes expresses completeness and togetherness, making them central to festival gatherings.

Some classic fillings were once considered luxurious or auspicious due to their cost, rarity, or meaning. For example, salted duck egg yolk inside a mooncake resembles the full moon and hints at potential wealth or good fortune.

Key Moments for Mooncakes in Chinese Traditions

Mooncakes are most famously associated with the Mid-Autumn Festival, the second most important traditional festival in China after Lunar New Year. On the 15th day of the eighth lunar month, friends and families present mooncakes as gifts and enjoy them under the luminous moon.

While the festival is the mooncake’s moment in the spotlight, they are sometimes enjoyed at weddings, business meetings, or as luxury gifts—especially when filled with exquisite ingredients.

Common Mooncake Fillings Across China

The diversity of China’s culinary landscape is reflected in its mooncakes. From sweet pastes to nutty mixtures, and even savory surprises, mooncake fillings are a showcase of local tastes and creativity.

1. Lotus Seed Paste (莲蓉 lián róng)

The Regal Classic

Lotus seed paste is perhaps the most iconic mooncake filling. Creamy, smooth, and sweet, it’s revered for its gentle flavor and satiny texture. Making authentic lotus paste is a labor of love: dried lotus seeds are soaked, boiled, and ground into a fine puree, then carefully cooked with sugar and a touch of oil.

This filling typically features in Cantonese-style mooncakes and is often combined with salted duck egg yolks to symbolize the moon. Originally a luxury because of the high cost of lotus seeds, this filling still represents a premium choice and is a must at many Mid-Autumn tables.

2. Red Bean Paste (豆沙 dòu shā)

Sweet, Comforting, and Universally Loved

Red bean paste is a staple throughout China, especially in southern regions. It’s made from adzuki beans boiled to tenderness and sweetened, resulting in a soft, slightly granular paste. The flavor is gentle, earthy, and appeals to those who love a more subtle sweetness.

Preferred by those looking for a plant-based delight, red bean mooncakes often feature in both traditional and modern baking styles.

3. Five Kernel & Roast Pork (五仁 wǔ rén)

A Crunchy Medley with a Storied Past

Five kernel (or five nuts) filling is one of the oldest and most traditional mooncake fillings. Its ingredients can vary but usually includes a mix of walnuts, pumpkin seeds, almonds, sesame seeds, and melon seeds, sometimes bound with crunchy candied winter melon or jujube paste.

For extra indulgence, roast pork or ham is sometimes added. The filling is chewy, fragrant, and full of texture, but its powerful flavor and bold style often divide opinions—some adore it, while others find it an acquired taste.

4. Salted Egg Yolk (蛋黄 dàn huáng)

Golden Centerpiece of Luck

Salty, rich, and with a taste reminiscent of cheese or caviar, whole salted duck egg yolks are either embedded in sweet lotus or red bean paste, or presented solo in the minimalist “single yolk” mooncake.

The yolk not only provides a dramatic visual, representing the full moon, but also adds a deeply savory and umami counterpoint to sweet paste. Double or even quadruple yolk mooncakes are considered extra lucky.

5. Jujube Paste (枣泥 zǎo ní)

Northern Comfort

Popular in the north of China, jujube (red date) paste mooncakes offer a dense, slightly tart-sweet flavor with subtle earthy notes. The paste is made by simmering jujubes until soft and then sieving them into a thick, glossy blend. This filling is beloved for its natural sweetness and nutritional value, as dates are rich in vitamins.

6. Black Sesame Paste (黑芝麻 hēi zhī ma)

Nutty Aroma and Silky Texture

Black sesame paste mooncakes feature a dark, glistening center with a powerful, toasted aroma and a uniquely smooth taste. This filling is favored by those seeking deep, earthy flavors and is sometimes blended with peanuts or coconut for added richness.

7. Taro, Yam, and Purple Yam Pastes

Violet Delights from the South

Mooncakes filled with taro, yam, or purple sweet potato pastes offer a naturally sweet and floral flavor with a striking color. Favorites in Southern China and among younger generations, these fillings offer a comforting texture and beautiful appearance.

8. Coconut Paste

Tropical Sweetness

Coconut lovers find their match in mooncakes filled with shredded coconut, often sweetened and blended with milk or white beans. The taste is creamy and bright, giving a tropical twist to the festival tradition.

9. Custard and Cream Fillings

Modern Innovations

Hong Kong’s beloved “custard mooncake” (流心奶黄 liú xīn nǎi huáng) is a relatively new but highly popular innovation. Its oozy, buttery filling is made from salted egg yolk, milk, butter, and sugar, creating a melt-in-your-mouth sensation and a delicate, modern flavor.

10. Regional Specials: Savory and Unique Fillings

China’s regional kitchens contribute signature mooncake varieties. Suzhou-style mooncakes often contain savory fillings like pork, scallions, or ham. Yunnan’s ham mooncakes are rich and salty, while some regions offer spicy or tangy options, such as pickled vegetables or chili sauce.

Regional Mooncake Styles and How They Differ

Throughout China, mooncake styles reflect local baking traditions and favorite ingredients. Let’s take a quick look at the most famous types:

• Cantonese-style: Thin, tender crusts with rich, smooth fillings like lotus seed, red bean, salted egg, or custard.
• Beijing-style: Flaky, thick shells featuring fruit pastes, nuts, or jujube.
• Suzhou-style: Flaky, puff pastry crusts with both sweet (like rose bean or black sesame) and savory (pork or ham) fillings.
• Chaoshan (Teochew) & Snow Skin: Delicate, sometimes “mochi-like” crusts with lighter fillings like mung bean, custard, or fruit.

Each style offers a different experience in taste and texture, making mooncake sampling a delicious journey in itself.

How Mooncakes Are Shared and Celebrated

Gift-giving is central to the Mid-Autumn Festival. Beautifully boxed mooncakes are exchanged among loved ones, neighbors, and business associates as blessings for harmony and prosperity. Eating mooncakes beneath the moon, while sharing stories or sipping tea, is a cherished tradition that brings people together.

Children may carry lanterns, elders retell folk tales, and every bite of mooncake is a communion with history and one another.
