點解菠蘿油要放入兩塊牛油??(10分)

1 piece is too thick, and not distribute in the bun, so u will feel oily in texture, and part of bun no butter will taste.

2pcs of butter will be better than 1, of course, in the basic operation, they will not spread a layer of butter as filling. It is a better way to do it and acceptable by majority of people and feeling satisfaction.

They can made u special when u have special request, it is hongkong style.

If the butter spread onto the bun directly, the butter will absorb by the bun easily and taste oily. So, using big piece of butter feel better.

Because it is yummy.
