So I got back and decided to try making a batch myself. The initial batch was too oily so I gave up and chucked everything into the fridge.
This morning however I cooked more rice and mixed it in. That made it better. Now my only problem was trying to get the rice the right flavour.
I'm super squeamish about adding too much vinegar or mirin (you DON'T WANT your rice to taste like it was the bastard child of a lemon and a packet of caster sugar). In the end, the rice was still slightly bland, but it's alright. I shall improve next time!
This round the stuffings were caramelised onions, diced and browned chicken franks and curry tuna (from a can lah. No time to cook. Hee).
The trick I used was something Mom taught me. You stick the rice into the corner or any plastic bag (preferably the kind you get from supermarts to put your veggies and fruits. Or you can use a ziploc bag), then use that to shape the dumpling. That's why the dumplings I made are this shape. Lol.
I think it still tasted quite good and it was fun making them. So give it a try if you're the kind who likes to have fun with your food.
Oh! DON'T forget to wash your hands before doing this. :)
