Baccalà Roll Sandwich

Method

1. Take the salt cod (baccalà) — it must be small and well soaked to remove excess salt and water.
2. Prepare the mayonnaise: in a blender, combine seed oil, one egg, pinches of salt, and lime juice. Start from the bottom and blend, gradually raising the blender until emulsified.
3. Finely chop fresh spring onion, basil (use a sharp knife or tear by hand), parsley, celery, and chili (remove seeds).
4. Mix the chopped herbs and vegetables into the mayonnaise.
5. Add lime zest and a pinch of salt to the mixture.
6. Cut two milk buns in half and lightly toast or warm them.
7. Spread some of the sauce (the mayonnaise mixture) on the inside of the buns.
8. Fill the buns with the baccalà and the remaining sauce.
9. Serve immediately.
