Baked Pastry with Red Bean Paste (红豆酥)

I had too much red bean paste in my fridge and I wanted to clear them.  That's why these pastries are being stuffed to their fullest!  

Ingredients

makes 15 pieces

Dough ingredients

2 cups regular flour

1/3 cup salted butter (soften at room temperature)

1 cup cold water

1/2 tsp salt

1/2 tsp white vinegar

Filling

red bean paste

Toppings

white sesame seeds

For brushing

1 beaten egg

Method

1. Mix the dough ingredients together in a big bowl with a large spoon or spatula.  Knead into a dough and let the dough rest for 30 minutes or more.
2. Dust some flour on a clean space and roll out the dough.  Divide the dough into 5 equal portions and then divide each portion into another 3 portions.
3. Roll out each small portion into a rectangular shape.
4. Place 2 tbsp red bean paste onto the centre of the roll-out dough, leaving some space at the two sides for pinching together.  
5. Fold the two long ends together, overlapping a bit and gently press to seal it. Turn it over.
6. Lightly press the other two sides to seal them as well.  Then use a fork to lightly press on both sides to make the pattern.  Repeat with the others.
7. Brush the top of the pastries with the beaten eggs.  Sprinkle some sesame seeds onto each of them.
8. Prepare a baking tray and lightly brush it with some melted butter.  Place the pastries on the tray.
9. Preheat oven to 375 degrees F and bake for 30 to 40 minutes or until they turn golden brown.
10. Transfer to a serving plate and serve warm or at room temperature.
