Mix the salt and sugar together. Spread a thin layer in the bottom of a baking dish. Layer the butterflied anchovies neatly on the salt/sugar mixture, skin side up, covering them with additional mixture as you go. Once you’ve managed to prepare them all, take a deep breath, have a glass of wine, and get ready to witness the magical transformative power of salt!
Cover the anchovies and refrigerate for 4 days. Sterilize 8 canning jars by boiling for 1 minute, then set aside to cool.
Remove the anchovies from the salt/sugar mixture and rinse carefully under cold running water. It’s very important that the water be cold, as bacteria can’t multiply in cold water and the flesh of the fish will also stay much firmer.
In a large bowl, combine the olive oil, garlic, pepper, lemon peel, herbs, and bay leaves. Layer the anchovies into the jars as carefully as possible, top each jar with the oil mixture, and evenly distribute the herbs and garlic.
Seal the jars, refrigerate and enjoy. They’ll keep a month or more in the refrigerator.
