👨‍🍳 Instructions

1. Rinse the pre-salted herring fillets under cold water to remove excess salt, then pat dry and slice them into 1-inch (2.5 cm) pieces.
2. Peel and thinly slice the red onion into rings.
3. In a saucepan, combine water, white vinegar, and granulated sugar; bring to a simmer, stirring until the sugar dissolves. Add bay leaves and allspice berries, then remove from heat and let the brine cool completely.
4. In a clean jar, alternate layers of sliced herring and red onion rings. Pour the cooled brine over the layers, ensuring the herring is fully submerged.
5. Seal the jar and refrigerate for at least 24 hours, preferably 2-3 days, to allow the flavors to meld. Serve chilled with boiled potatoes or crispbread.
