I also cook sinigang but mostly I prefer sinigang na baboy, it takes time to soften the pork but the outcome would be delicious, I am using sinigang sa gabi which had combination of taro which makes the dish more delicious, I also cook sinigang na bangus which is the easiest one.

The way of your cooking sir is different from mine but I guarantee that yours is more cleaner and faster, I hope I can taste that dish of yours sir cause I'm sure it's delicious.
