From a blogger’s recipe (English and Japanese):
So, I finally made this cute treat this afternoon. It was not hard to remove the almond skin after couple minutes in hot water. But you do need a good/powerful grinder to grind the almond into mill.
今天下午終於有空來試來自瑞典的格友她的食譜. 杏仁在沸水泡過兩三分鐘後去皮就很容易. 最好是有馬力強大的機器,能夠很快把脫皮後的杏仁磨成粉.
300g almond mill or 300g nut mill (200g almond + 100g other desired nuts)
200g icing sugar
1 egg white
1 teaspoon pure almond extract
1.Mix well into clay like dough. Seperate the dough into equal portions, roll them into balls.
I used 72% dark chocolate 100-150g
2.Melt the chocolate in a bowl on top of pan contain boiling water.
1 baking tray
wax paper or parchement paper on the tray for easy peel
some pecan halves (garnish one pecan half in one small ball)
3.Drop the balls into the chocolate bowl to cover the chocolate. Take the balls out, put them one by one on the tray. Garnish the chocolate covered ball with one pecan half. You can enjoy them after chocolate dry and firm. They are cute to look at and tast very nice, the chocolate cover is hard and the soft nutty center is just right sweetness!
3.置入小球使裹上巧克力漿,撈起後置於烤盤紙上,取一胡桃仁剖片塞入中間約1/2-1/3依胡桃仁大小調整深度. 乾後定型後即可食. 定型後的巧克力脆而香濃包著裡面的堅果軟心. 甜度恰到好處!
