How a viral Taiwanese rice ball in California led the world into Taiwan’s breakfast culture

A breakfast staple familiar to virtually every Taiwanese person has unexpectedly become a sensation in California.

Recently, a Taiwanese sticky rice ball (紫米飯糰), went viral in California after food creator Danny shared a video of himself trying one at a Taiwanese restaurant. Packed with ingredients such as fried dough sticks, pork floss, sausage, and egg, the oversized rice ball impressed viewers with both its flavor and its size. Even though the fully loaded version cost more than US$10, Danny described it as affordable and delicious, helping spark curiosity among American diners.

The viral video quickly drew attention beyond Taiwan's immigrant communities. According to local reports and social media posts, more non-Taiwanese customers have begun visiting Taiwanese breakfast shops to try the dish for themselves. 

The trend even caught the attention of Hollywood actor Simu Liu (劉思慕), best known for portraying the Marvel superhero Shang-Chi, who was reportedly among those making a visit to try the viral rice ball.

Yet while American food lovers were celebrating their new discovery, many Taiwanese viewers had a different reaction. Instead of discussing the taste, they joked about what happens after eating a rice ball.

Taiwan's "carb coma" warning

Taiwanese internet users quickly filled the comment sections with warnings. Some joked that a rice ball this size could make you "sleep until dinner," while others claimed that "if everyone started eating these, anesthesiologists would be unemployed." Many described it as "the ultimate sleeping pill" and a guaranteed shortcut to a carb coma.

While clearly exaggerated for comedic effect, the jokes are rooted in a familiar experience shared by many Taiwanese: feeling unusually sleepy after a large, carb-heavy breakfast.

The joke revolves around a popular term known as "carb coma" — the feeling of becoming sleepy or sluggish after eating a meal rich in carbohydrates. While the phrase is often used humorously, there is some science behind it.

Traditional Taiwanese rice balls are typically made with sticky rice or a mixture of sticky rice and purple rice. A single rice ball can contain roughly the same amount of rice as an entire bowl of rice, along with fillings such as fried dough sticks, pork floss, eggs, and sometimes sausage. The combination creates a meal that is both high in carbohydrates and relatively high in fat.

After consuming a large amount of carbohydrates, blood sugar levels rise, prompting the body to release insulin. For some people, the subsequent drop in blood sugar can contribute to feelings of fatigue or drowsiness. Meanwhile, fatty ingredients can slow digestion and leave people feeling especially full. Together, these factors help explain why many Taiwanese jokingly associate rice balls with an irresistible desire to take a nap.

What's inside a Taiwanese rice ball?

Although recipes vary from shop to shop, a traditional rice ball usually contains a combination of ingredients that reflects Taiwan's diverse culinary influences.

The outer layer is made from warm sticky rice, sometimes mixed with purple rice for additional texture and flavor. Inside, common fillings include crispy fried dough sticks (油條), savory pork floss, pickled vegetables, and egg. Some shops also add sausage, braised pork, preserved radish, or spicy condiments.

The result is a breakfast that combines soft, chewy, crunchy, salty, sweet, and savory elements all in a single bite.

For many visitors, the closest comparison might be a breakfast burrito. Both are portable, filling morning meals wrapped around multiple ingredients. However, where a burrito relies on a tortilla, Taiwan's version uses rice as its foundation, giving it a distinctly East Asian character.

More than just breakfast

The rice ball's popularity also offers a glimpse into Taiwan's unique breakfast culture.

One characteristic of Taiwanese breakfasts is their emphasis on carbohydrates. Rice, wheat-based flatbreads, fried dough sticks, steamed buns, pancakes, and noodles all commonly appear on breakfast menus. For many Taiwanese, a substantial, carb-rich breakfast is seen as a practical way to stay energized throughout a busy morning.

Unlike in many Western countries, where breakfast is often eaten at home, many Taiwanese grab breakfast from neighborhood shops on their way to work or school. These small eateries open before sunrise and serve a wide range of freshly prepared dishes at affordable prices, making them a daily ritual for millions of people.

While rice balls may be one of Taiwan's most iconic breakfast items, they are far from the only option. A typical breakfast shop menu might also include:

Soymilk (豆漿) — Served hot or cold, sweetened or unsweetened. Many locals also enjoy savory soy milk, a comforting dish flavored with vinegar, dried shrimp, pickled radish, and cilantro.

Egg crepe (蛋餅) — A thin, chewy pancake wrapped around egg and fillings such as cheese, ham, tuna, or corn, often topped with soy sauce or chili sauce.

Deep-fried dough sticks (油條) — Crispy fried dough sticks commonly dipped into soy milk, wrapped in sesame flatbread, or tucked inside a rice ball for extra crunch.

Radish cake (蘿蔔糕) — Savory cakes made from shredded daikon radish and rice flour, pan-fried until golden brown on the outside and soft on the inside.

The variety reflects Taiwan's diverse culinary influences, blending traditional Chinese breakfast foods with local innovations and even Western-inspired items such as burgers and sandwiches.
