Baking Time - Potato Bread

Unfortunately, I didn't manage to take a picture of my end products. It looks fairly good, NOT UGLY at all. Hehehe

Let me recall the ingredient & Procedure

Ingredient :-
For the Dough
1. 300gram Flour
2. 40gram Sugar
3. 180ml Cold Milk
4. 25grams of Butter
5. 1/2 tsp Salt
6. 4gram Yeast
7. 60grams Raisin
8. 100gram Mash Potatoes

For the Custard
1. 100gram of INSTANT Custard Powder
2. 250ml Water
3. 1 egg to brush on the dough

Procedure :-
1. Mix the Yeast, Flour, Sugar, Salt & Mashed Pototoes
2. Pour in the cold milk slow and mix until it forms a Dough
3. Mix the Butter until the Dought become smooth, then add in the Raisin
4. Proof the Dough for 50mins until it doubles its size
5. Split the dough into a bun weight around 50gram each.
6. Proof these little buns for another 50mins until they double their size.
7. Brush the bun with eggs
8. Mix 250ml water with INSTANT Custard Powder until it is thicken
9. Squeeze the Custard Mixture on top of the Bun
10. Place the buns into the Preheat Oven @ 180deg C
11. Bake for 25 mins
12. Cool them at the wire rack
13. EAT!

Lesson :
(1) I was greedy, i used more than 100gram of Mashed potato, perhaps it was the reason which hardened the bun a little.
(2) I failed the Custard Part. I am not sure whether the recipe is wrong or my Custard Power is not INSTANT (yet to find out the difference).
(3) Overall Yummy, easy to make but not soft enough.
WILL TRY AGAIN.
