Where to buy football/quenelle/shell-like scoop/mold/mould [food presentation]? Some places serve rice in a football/quenelle/shell-like shaped scoop/mold/mould for food presentation. It's consistent at many teriyaki places so I suspect it's something you can purchase.

I've searched for the following terms: football, shell, prolate spheroid, oval, quenelle, in conjunction with scoop, mold/mould but haven't had any luck.

The closest I've found is a "Deep Boat Petit Four Mould", but the bottom is flat instead of a dome.



Edit: This is used to mold sticky rice, ideally they would have the 'shell like' ridges running longitudinally/lengthwise). All of these teriyaki pictures are from the Seattle area.

Update (2016-06-19): Found the mold in use in Japan. It's commonly used in omurice.

There is a technique called quenelling where you form this shape using two spoons. It appears to be usually used for ice cream and other items of similar consistency but I don't see why it wouldn't work for steamed rice (although those would have to be large spoons).
