Any tips from this recipe?
Matchsticks, not slices. The thin sticks cook evenly and hold the cream between them. If the top is brown but the middle is still firm, it needs more time at a lower heat, not less time. Swedish grocers abroad and IKEA food halls sell the proper ansjovis tins around Christmas.
Can I prepare this ahead?
It reheats well and is arguably better the next day.
Can I use an air fryer?
This method is not written for an air fryer. The core technique on the page still applies.
