Doughnuts - Japanese gelatinised-dough method

I'd been searching high & low for Alex Goh's Magic Bread in bookshops here in Singapore as well as in Malaysia ever since I made the Chicken Floss Buns. Finally, I found it at a Popular branch recently. Didn't have to think much.... I just took a quick browse & paid for it. 

All the recipes in this book use the gelatinised-dough method in which part of the dough is cooked in boiling water & left overnight before adding to the rest of the ingredients. It was introduced by the Japanese chefs & like many Japanese bread, the texture of the bread using this method is supposed to be soft & springy without having to add bread improver & chemical food additives. I was quite surprised there's also a doughnut recipe using this method. Naturally, I became quite curious with how the doughnuts would turn up. 

So last weekend, I made a batch of sugar doughnuts using the recipe in the book. As expected, the doughnuts turned out very soft, especially when eaten within a few hours from frying them. After almost 24 hours, the texture of the doughnuts was denser but they were still delicious.

Doughnut 

Gelatinised dough:
100g bread flour
70g boiling water

Pour boiling water into flour & mix until well blended to form a dough. Cover & set aside to cool. Then keep it in the refrigerator for at least 12 hours.

Dough:
250 g bread flour
150g plain flour
10g milk powder
1 tsp baking powder
50g sugar
8g instant yeast
1 whole cold egg
160 g cold water
50g butter
6g salt
cooking oil for deep-fry

Method:

1. In a mixing bowl, combine bread & plain flour, milk powder, baking powder, sugar & instant yeast & mix well. 
2. Add in egg & cold water & mix until  a rough dough is formed. Add in gelatinised dough & mix until well blended.
3. Add in butter & continue mixing well. 
4. Finally, add in salt & continue mixing to form a smooth & elastic dough. Check for membrane.
5. Remove from bowl & mould into a smooth round dough.  Place the dough into a greased bowl, and cover. Set in a warm place to rise until double. Dough is ready if you touch it, and the indention remains.
6. Turn the dough out onto a floured surface,  mould into a smooth round dough & leave to rest for 10 minutes. 
7. In the meantime, cut grease or baking paper into pieces, each slightly bigger than the doughnut cutter. Sprinkle with flour. 
8. Gently roll out the dough to 10mm thickness. Cut with a floured doughnut cutter. Place cut doughnuts onto the grease or baking paper. Place on a tray. Let doughnuts sit out to rise again until double. Leave to proof for about 30 minutes.
9. Heat oil in a deep-fryer or large frying pan. Slide doughnuts into the hot oil.  Turn doughnuts over as they rise to the surface. Fry doughnuts on each side until golden brown. Remove from hot oil & drain on a wire rack.
10. Leave to cool slightly. Then sprinkle doughnuts with sugar or decorate top with chocolate.
