Where to buy Sushi making equipement
My son's birthday and he wants to make his own sushi.
Most large grocery stores have a sushi section which will have bamboo mats, nori, and seasoned vinegar. That's pretty much all you need equipment-wise, apart from a sharp knife and whatever ingredients you choose to fill your sushi rolls with. Don't forget to cover the bamboo mats with plastic wrap to prevent the rice from sticking to it!
Tap Phong trading would likely have most of what you need at reasonable prices. I purchased a sashimi knife there at a good price and it is serving me well.
