To make 'sticky' rice, is it essential to have a rice cooker? I want to try to make rice cakes for big rides as I'm getting sick of sweet energy bars etc.

The recipe from the below specifies using a rice cooker and sushi style rice; if I get the right type of rice is there another way of cooking it that will produce the same kind of effect?

Ta in advance

I've used this, it's amazing, but in my experience took a bit of trial and error
