My auntie used alkaline rocks instead of the ready alkaline water in bottle. She told me that bottle type would give stronger alkaline taste. So, we had to dissolve the alkaline rock in water. You could just use alkaline water if you could not find the alkaline rock.
The day before, we had to pick out all the white rice from the glutinous rice so that we have pure glutinous rice. We did not soak the glutinous rice, but just washed it. The glutinous rice was then mixed with alkaline water and cooking oil until it was light yellow in color.
Do not add too much alkaline water, else it would have strong alkaline taste.
We could not find the exact leaves for alkaline dumpling so we used the same leaves as meat dumpling. We used the bigger leaves for meat dumpling and kept the smaller leaves for alkaline dumpling.
My alkaline dumpling did not get rejected this time. Yesterday, my auntie had to check my dumplings one by one and re-wrapped some of them. I would say it was much easier to make alkaline dumpling.
We finished turning all the glutinous rice into alkaline dumpings before noon time.
Then, my auntie placed all the dumpings into the boiling water.
The boiling process took about 4-5 hours. I will blog some photos of the unwrapped dumplings if I have time.
