since I can't do a *cook*-along for sushi, this is a *roll*-along.
First, season your warm cooked rice with some rice vinegar (I used about 2 T for 4 cups or so of rice) and a little sugar if you like. Taste to see if it's seasoned enough.
Next, gather all your ingredients. I have a bowl of seasoned rice, avocado, fake crab, and cucumber, and a package of nori (dried toasted seaweed sheets). I use a cutting board to roll on, and I have a small bowl with water and a spoon, and a large knife for cutting my filling.
Cut your fillings into matchstick peices. I even cut my crab into slices b/c it makes it easier to roll evenly.
On the cutting board (or on top of a bamboo mat if you prefer, or even right on the counter) lay out of piece of nori, spread a layer of rice to the edges, leaving about an inch at one end. Press it down with the back of a wet spoon and/or wet fingers. Lay your fillings out close together in a line at one end. ~Having the rice packed down, and the fillings close together makes it easier to get a tight roll so your fillings won't fall out.
slightly wet the end of the nori without the rice and starting from the filling end, tightly roll
and press the damp end onto the dry part to seal. The damp part will really stick to the dry part so it won't come apart.
set the roll on a plate to the side and finish rolling the rest
When you are done, slice each roll into 1 or 2 inch rounds and set out on a plate
top with soy sauce, or mix a little blob of wasabi into a bowl of soy sauce to make a dip
You can use anything you want for filling. I prefer avocado, crab and cucumber but I've used teriyaki chicken and made a sauce with a little bit of mayo and teriyaki, and I also like just plain avocado. Seasoned tofu would be really yummy for a veggie cal. roll, or you could do any veggie you wanted.
