The sweetness of the paste was ok: not too sweet. However, the coffee flavour wasn't that strong. Despite this, my two boys love them very much. My elder boy remarked that the rolls resembled like a "caterpillar" ;) and he wanted to bring it to school tomorrow :)
On closer look, it did resemble a caterpillar :)
Recipe as follows:
1 qty "basic sweet bun dough
250g red bean paste
some sesame seeds
1 egg (beaten)
some white sesame seeds
1. Leave dough in a big bowl, covered with a damp cloth. Proof in a warm place for 30 mins till dough is double in size. Scale dough at 60g portions. Shape them into small balls and rest the dough balls for five mins.
2. Flatten and roll each ball of dough into a round. Place in a little filling, seal and wrap into a round. Roll flat once more and make several slits (use a dough cutter). Roll up and place on a greased baking tray. Repeat process with the rest of the dough. Cover with a damp cloth and leave them for 45 mins to rise a 2nd time.
3. Glaze with egg wash and sprinkle top with sesame seeds. Bake in a preheated oven at 180 deg C for 12-15 mins. Tray should be placed in the middle rack of the oven. Remove when golden. Cool well on wire rack.
