Sweet-and-sour strawberries generously coated in a powdered salt of chili and dried shrimp. It's a scene long seen on Vietnam's streets, but it caught fire through short TikTok videos, leading to a flood of review videos being posted. We dig into why this snack, called "Dau Lac Muoi Tom," is going viral mainly among Vietnam's Gen Z.
What is shrimp salt (muoi tom)?
Muoi ot tom (Muoi Ot Tom) is a seasoning blending salt, chili, garlic, sugar, and dried shrimp. Tay Ninh Province is considered its home, and its history dates back roughly 80 years.
Its origin lies in the French colonial era, when it was prized as a preserved food that soldiers carried along with rice. It also circulated as a treat for guerrilla fighters during the Vietnam War. In 2023, Tay Ninh Province's muoi tom was recognized as "national intangible cultural heritage."
| Ingredient | Role |
|---|---|
| Dried shrimp | Umami and powdery sweetness |
| Chili | Heat and a sharp, tingling aftertaste |
| Salt | The base of the flavor |
| Garlic | Fragrant aroma |
| Sugar | A balancer that softens the edge of the heat |
| Lemongrass (in some products) | An accent of refreshing flavor |
The key to the process lies in the "roasting" step. After mixing the ingredients, they are dry-roasted in a pan for about 15 minutes while stirring constantly. This heat control decisively shapes the flavor.
Why strawberries?
In Vietnam, dipping fruit in salt is an everyday habit. Combinations of muoi tom with tart fruits — mango, guava, green apple, watermelon, pineapple — have long been staple street-stall menu items.
Behind strawberries drawing attention is the expanded distribution of Da Lat strawberries. The cool highland region of Da Lat is Vietnam's largest strawberry-growing area, and supply to supermarkets in Ho Chi Minh and Hanoi has become steady. Their affordable price and vivid red color are TikTok-friendly, and they spread as photogenic material.
The structure of going viral on TikTok
Snacks that go viral on TikTok share a common pattern.
- Three or fewer prep steps: Wash the strawberries → coat with muoi tom → eat. It wraps up in a 15-second video
- An ASMR element: The gritty texture of the muoi tom comes through in sound
- Reaction appeal: The confused faces of foreigners tasting it for the first time — "sweet? spicy? salty?" — rack up views
- Cheap ingredients: Complete with one pack of strawberries plus one bag of muoi tom. The barrier to entry is near zero
Beyond strawberries and muoi tom, Thai-style mango rolls and tart-and-spicy snacks made with tamarind paste are trending at the same time. The trend of Gen Z shifting from "just sweet" sweets to complex "sour + spicy + salty" taste experiences is made visible on TikTok.

To try it in Japan
Muoi tom can be bought at Asian grocery stores in Japan or on Amazon. Domestic strawberries work fine.
The way to eat it is simple. Cut a strawberry in half and lightly coat the cut surface with muoi tom. Since too much lets the heat dominate, it's best to start with a small amount.
It works with mango and kiwi too. The more tart the fruit, the better it pairs with muoi tom.
