Saute carrots in melted butter for 1-2 minutes. Add onions.
Add 2 cups of cold water and season. Arrange slices of mackerel fillet on top of (or mackerel steaks dipped into) the vegetable layer. Lower the heat to min. Cover with a lid and slowly cook for 15 minutes.
Turn off the heat, add cream, garnish with scallions and parsley (if using) and keep covered until cooled down to the room temperature.
Serve warm or cold with sliced crusty bread. Enjoy!
