Dim sum is a Cantonese dining tradition of small, shareable dishes commonly enjoyed with tea. The Cantonese term dim sum (點心) literally suggests "touching the heart," and the meal format emphasizes many modest portions meant for sharing. It is most often eaten at breakfast or lunch during a yum cha (tea-drinking) outing, where tea and conversation are as important as the food.

Characteristics and typical items

Portions are small and diverse, often prepared to showcase a particular technique or ingredient. Dishes are presented in bamboo steamers, on small plates or on platters, and may be steamed, pan-fried, deep-fried or baked. Common examples include:

  • Steamed dumplings such as har gow (shrimp) and siu mai (pork and shrimp)
  • Buns and rolls like char siu bao (barbecue pork bun) and cheung fun (rice noodle roll)
  • Fried and baked items such as spring rolls, egg tarts and turnip cake

Service styles and etiquette

Traditional service uses pushcarts or trolleys from which servers present dishes to each table, but many modern restaurants use menu ordering or electronic tablets. Diners typically take several different items to share; plates are replenished and a ticket or chop system records consumption for billing. Common etiquette includes pouring tea for others, sampling a variety of items, and avoiding waste.

Origins and geographical spread

Dim sum developed from teahouse culture in southern China—especially the Guangdong region and Hong Kong—where travelers and laborers stopped for tea and small bites. Over the 20th and 21st centuries, the custom spread with Chinese communities worldwide and adapted to local tastes in places such as Malaysia, Singapore, and North America.

Importance and variations

Dim sum reflects regional ingredients, culinary skill, and social dining habits. While strongly associated with Cantonese cuisine, variations exist: some cities emphasize steamed dumplings, others focus on baked pastries or larger, heartier plates.

Note: Recipes, presentation and mealtime customs vary by region and restaurant, so newcomers are encouraged to ask servers for recommendations and sample a range of items.
