That evening before PAi Ti Kong, I went to an Ang Ku wholesaler with my auntie.
This is what we saw in that crowded shop that makes ang ku in bulk.
Apparently, most of the ang ku in trays were already pre-ordered. Since auntie only wanted to buy a few..they have enough to spare us.
There was a machine to make the greenpea paste & another that mix the ang ku dough.
Emmm indeed very eye opening for a first timer like me to visit this shop.
Besides Ang Ku, they also have these kuehs for the offerings during pai ti kong:
