Sardines ("kilu") are very common out here in Tallinn, and are very commonly eaten raw (e.g. kiluvõileib). It's particularly easy (and cheap) to find whole sardines that you can filet yourself. I have tried this at home in the following steps:
- Cut off the head.
- Slice open the belly.
- Remove gizzards and nonsense from belly.
- "Unfold" the sardine.
- Using a fork, grab the spine at the head-end of the fish and pull it straight out.
- Spend several minutes collecting bazillions of leftover rib bones, one-by-one, for each tiny fish.
The final step is obnoxious. I must be doing something wrong. How do I get the ribs out of the fish, efficiently?
