Molten Lava Bun

 
There is something really satisfying about making (and eating) your own buns, especially these molten lava buns. The “molten lava” is none other than the ever popular salted egg yolk custard filling. I had a fun time making the step-by-step video below, especially the part where I get to pry open the buns to reveal the filling inside. Also, I made a new friend that day called Calories.

The last time I ate these fluffy buns were with my bestie at Crystal Jade Kitchen couple months ago. Unlike the traditional snow-skinned buns served in most Dim Sum restaurants, theirs had an orange-y hue. That visit totally inspired me to recreate them in my kitchen. I mimicked the color on another batch with the addition of pumpkin and I think it worked!

With or without the pumpkin, I’m totally loving both versions. I prepared the salted egg custard the day before as they need to be chilled in the freezer overnight before filling them in the dough. You could definitely prepare them few days in advance and keep them frozen until ready to use.

You could make them into bigger or smaller sizes, just take note the ratio of the bun to filling is 2:1. Example: 40 g dough:20 g custard. This recipe makes 12 x 40 g buns.

If you ask me, these buns are pretty good enough to pass off as a satisfying homemade product. Even without the use of emulsifier (the agent responsible for producing soft, fluffy texture from commercial buns), they stayed relatively soft even when cooled.

You could store them in the fridge or freezer (for longer period) and simply steam them again before consumption.

 

Ingredients:
For buns –
300 g Superlite flour / Hong Kong pau flour
3 g baking powder
3 g instant yeast
45 g caster sugar
160 ml water (add more if the dough is too dry)
15 g vegetable oil
For pumpkin bun version, please include the ingredients below:
100 g cooked pumpkin + 16 g butter – mash together

Recipe adapted from: Happy Home Baking & Savory Days Kitchen

Custard:
Prepare the custard but separating the salted egg yolks from the whites. Rinse them gently under running water.

Place them in a heatproof bowl and steam over high heat for 10 mins.

When they are slightly cooled, add in butter, condensed milk and milk powder.

Mix until smooth. If you prefer the custard to be sweeter, adjust with more condensed milk.

Place them in the refrigerator to chill until firm. Mine took about 45 mins in the fridge.

Take them out and use a spoon or ice cream scoop and divide into 20 – 22 g each.

k

 

Place on a baking tray lined with cling wrap and cover with another layer of cling wrap.

j

 

Freeze until hard for at least 6 hours or preferably overnight.

Buns:
In a large bowl, add the flour, baking powder, sugar, yeast and whisk together.

Add in water, vegetable oil and using an electric hand mixer or stand mixer, mix until a dough ball is formed, approx. 10 mins.

It should be smooth and elastic. Alternatively, you could knead with your hands too and that will take about 15 – 20 mins.

Dust the counter lightly with some flour and take the dough out from the mixer. Knead it lightly for another minute until smooth and not sticky.

Shape dough into a ball and place it in a large bowl greased with a little oil.

Cover with cling wrap and let it rise at room temperature for 30 mins. I like to leave it in my oven or microwave.

Use a finger and poke into the dough. It should create an indentation without bouncing back.

Press down the dough to release the air and take it out from the bowl and gently knead into a log shape.

Divide dough into 12 portions, 40 g each. Use a weighing scale.
