Not quite true, both are fermented soy beans, but
dau si = dry individual beans that are black in colour
meen si = beans in a paste that is brown in colour
To use dau si, you have to rinse and mash them, and usually fry them.
So some companies like Lee Kam Kee has made dau si sauce in a bottle
which saves you all these steps. Dau si has a stronger flavour, while
meen si has a fuller rounder flavour.
