Tau Sar Piah (豆沙饼)

Wednesday, 19 July 2017

In Penang, Tau Sar Piah (a.k.a. Tambun Biscuits) are baked flaky pastry biscuits filled with a sweet or savoury filling made from grounded mung beans (tau sar). We had a lot of mung beans left over from making bak chang by my mother in-law. So, I decided to use it to bake my healthy version of Tau Sar Piah where no shortening or pork lard used.

Recipe adapted from Jane’s corner  and Yum Cookbook with some modifications.

Yields: 36 biscuits



400g split green beans (mung beans)
250g brown sugar
2 tsp salt
1 ½ tsp pepper

10 shallots (sliced thinly)
100g cooking oil

Water Dough (A):
250g all-purpose flour
½ tsp brown sugar
65g sunflower oil or cooking oil
120ml – 130 ml water

Oil Dough (B):
165g all-purpose flour
70g sunflower or cooking oil

Egg wash: 1 egg + 1 tablespoon water
Some white and black sesame seeds


To prepare the mung bean filling:

1.  Wash and soak mung beans in water for at least 4 hours or overnight. Drain well and steam at medium heat for 40 minutes till soft.

2.  In the meantime, fry the shallots with oil till fragrant and golden brown. Remove from wok and crash the fried shallot with spoon or hand. Set aside.

3.  Mash the steamed mung beans till very fine while still hot. Add brown sugar, salt, pepper and fried shallots (plus the oil) and mix well.

4.  Divide the filling into 36 portions and shape into a ball.

To make the Tau Sar Piah:

1.  Knead ingredients (A) and ingredients (B) separately into a smooth dough by hand. Let them rest for 10 to 30 minutes.

2.  Divide the dough into 36 portions for each dough, around 11-12 g for water dough (A) and 6-7 g for oil dough (B).

3.  Flatten dough A and wrap up dough B. Roll skin into a rectangular shape, roll up like swiss roll. 

4.  Repeat another time the same way.

5.  Roll skin into think rounds, wrap up 1 part of filling and form into a ball. Slightly flatten them and arrange onto a baking tray. Brush with egg wash, leave till almost dry and brush again with egg wash. 

6.  Lastly sprinkle some sesame seeds on top.

7.  Bake in a preheated oven at 180C for around 30 minutes till golden brown.
