X ManOctober 11, 2024050 views

Introduction

The Pineapple Bun, known as "Bolo Bao" in Cantonese, is a beloved pastry found in bakeries throughout Hong Kong and other Chinese communities worldwide. Despite its name, this charming sweet bun carries no traces of pineapple inside; instead, it boasts a unique crunchy topping that resembles a pineapple’s texture, making it both delightful to taste and visually appealing. Typically priced between $1-$3 at local bakeries or dim sum restaurants, you can enjoy this treat at renowned spots like Kam Wah Cafe or Australia Dairy Company. Nowadays, with the rise of keto diets, many are on the hunt for a delicious keto version of the Pineapple Bun that doesn’t compromise on flavor or texture.

Origin and Inspiration

The Pineapple Bun’s origin traces back to the streets of Hong Kong during the 1940s, where bakers experimented with various toppings for sweet yeast buns. Surprisingly, the inspiration for its name came not from the fruit itself but from the bun’s distinctive golden-brown, crunchy topping that mimics the exterior of a pineapple.

Across Asia, variations of sweet buns can be found—from Japan’s Melon Pan to Taiwan’s Pineapple Cake—but the Hong Kong Pineapple Bun stands out with its airy, fluffy interior that contrasts beautifully with its crispy topping. For those avoiding carbs, the keto Pineapple Bun adaptation cleverly uses almond flour and erythritol to create a healthier yet equally satisfying version, keeping the original’s delightful flavor and texture intact.

Nutrition Info (Per Serving)

Traditional Version

Keto Version

Ingredients (2 Servings)

Shared Ingredients:

1 ½ cups all-purpose flour (or almond flour for keto)

1/2 cup milk (almond milk for keto)

1/4 cup sugar (erythritol for keto)

2 tsp yeast

1/4 cup butter (or coconut oil for keto)

1 egg

1/4 tsp salt

Topping ingredients below

Traditional Version:

1/2 cup sugar

1 cup all-purpose flour

1 egg yolk

2 tbsp butter

Keto Version:

1/4 cup almond flour

1/4 cup coconut flour

1 tbsp erythritol

1 egg yolk

2 tbsp melted coconut oil

Instructions

1. Prepare the Dough:

Traditional Version: In a mixing bowl, combine flour, sugar, and salt. In a separate bowl, mix warm milk and yeast, letting it froth for about 5 minutes. Add melted butter and an egg to the dry mix. Gradually add the yeast mixture, kneading until you have a soft dough. Allow it to rise for 1 hour or until doubled in size.

Keto Version: Follow the same steps but substitute the all-purpose flour with almond and coconut flour. Ensure the dough is slightly tacky, making it easy to handle.

2. Prepare the Topping:

Both Versions: Mix topping ingredients (sugar, flour, and butter for the traditional; erythritol, almond flour, and coconut oil for the keto) until they form a crumbly mixture. Ask the dough to rise separately for 20 minutes while you prepare the topping.

3. Shape the Buns:

Roll the dough into round balls, each about the size of a golf ball. Place them on a lined baking sheet, leaving space between. Gently flatten and top with the crumbly topping, making a distinct grid pattern to capture that pineapple appearance.

4. Final Cooking and Serving:

Preheat your oven to 350°F (175°C). Bake for around 15-20 minutes or until golden brown. Breathe in the sweet buttery aroma as it fills your kitchen, making every bite worth the wait! Let the buns cool on a wire rack before indulging in their warm sweetness.

What Does It Pair Well With?

Traditional Pairings: A cup of warm milk tea or a bowl of sweetened condensed milk for dipping creates a delightful brunch.

Keto-Friendly Pairings: Enjoy your keto Pineapple Bun with a refreshing iced herbal tea or a side of mixed berries for a light, balanced treat.

What is the Shelf Life?

Pineapple Buns are best enjoyed fresh. However, they can last in an airtight container at room temperature for up to 2 days. For longer storage, you can freeze them for up to 1 month. Reheat in the oven for about 5 minutes to maintain their fluffy texture.

Alternative Cooking Methods

Oven: The classic method yields perfect results.

Air Fryer: A modern approach that can reduce cooking time to about 10 minutes, giving you that golden crunch.

Steamer (for Keto): If your dough feels too dry, steaming can moist the buns without compromising their unique texture.

Conclusion

The Pineapple Bun celebrates the delightful interplay between a fluffy interior and a crunchy topping, making it a cherished treat among many. Whether you indulge in the traditional recipe or opt for the keto adaptation, this sweet bun proves versatile without losing its charm. Enjoying a Pineapple Bun evokes warmth and comfort in each bite, making it a fabulous addition to any meal or snack. Make them fresh, pair with your favorite beverages, and relish in the satisfaction of a deliciously homemade treat!
