Compressed Rice with Smoked Salmon

I found a recipe for compressed rice with smoked salmon in a Japanese cookbook that I've been keeping. I didn't have the special equipment, so I put saran wrap over the top and put jars on top. Eric says that since it came out uneven, I should practice every week until I get it right. Maybe I'll buy the equipment. Maybe I'll just try out bigger jars.
