I made a mistake. I thought this snack was luk chin pla, or fish balls, but was sorely mistaken. They were pork. My bad. Anyhow, I was drawn to this vendor due to the fact that they were being steamed right then and there, as opposed to grilled, as I've covered before when I declared snacks like these a desperation snack.
When prepared in this way, they are tender as opposed to rubbery like the grilled version. Topped off with a spicy sauce, they're quite alright.
