re: There are many, many macaroni others but smaller...
If you look carefully at the image (the complete image) you will see plenty of macaroni (much smaller though). I tried to post an annotated image (the "Macaroni Soup" posting) where I circled out several of them but it seems that uploading images is not allowed. These other "macaroni" in the image are smaller than the big one and they also look as cemented grains.
