Salted egg sponge cake has long been one of Vũng Tàu’s most beloved specialties, a must-buy treat for travelers looking to bring home a taste of the seaside city. What makes this humble pastry so unforgettable is its signature combination: a soft, airy sponge paired with rich, savory salted egg yolk, balanced sweetness, and optional toppings like pork floss or cheese that elevate the flavor even further.
What truly sets Vũng Tàu’s salted egg sponge cake apart is the traditional baking method. Many local bakeries still use wood-fired ovens fueled by coconut shells, creating a uniquely fragrant aroma that no modern machine can replicate. Thanks to its delightful taste, easy-to-eat texture, and good shelf life, the cake has earned its status as a “national favorite,” often passed along by word of mouth as a must-try local specialty.
And if you’re planning to bring some home, proper storage is key to keeping the cake soft, moist, and flavorful.
How to Store Vung Tau’s Salted Egg Sponge Cake Properly
1. Suitable storage time
- At room temperature (25–28°C):
The cake stays fresh for up to one day in a cool, dry place. If the weather is hot and humid, it’s best to refrigerate it. - In the refrigerator (0–4°C):
The cake keeps well for 3–5 days. Before eating, let it sit at room temperature for 10–15 minutes or warm it briefly in a microwave or oven to restore its softness.
2. How to pack the cake if not consuming immediately
- Wrap the cake tightly with plastic wrap or place it in a zip bag to retain moisture.
- Store it in an airtight container to avoid absorbing odors from the fridge.
- Keep it away from strong-smelling foods like garlic or onions.
3. Signs the cake is no longer good
- The texture becomes dry and hard.
- Visible mold or unusual smells.
- A sour or bitter taste.
If you notice any of these signs, it’s best not to consume it.
Pro tip: Salted egg sponge cake is always best enjoyed on the same day—taste it fresh to experience the full, rich flavor that makes Vũng Tàu’s version so iconic.
