Pre-heat oven to 320F/160C
In a bowl, mix together all the ingredients for the marinade to make a thick paste
If it’s too thick, add more lime juice or 1-2 tsp water to make it spreadable
Wash and pat dry the salmon fillet
Cut out a piece of aluminium foil large enough to wrap your salmon fillet
Take a baking pan (I use a pyrex glass baking pan) and place the aluminium foil inside
Place the salmon in the foil
Marinate generously with the marinade paste using your fingers or a pastry brush
Pour a few drops of oil on top if the marinade looks too dry
Cover with the aluminium foil
Bake in the pre-heated oven for 15-20 mins for the salmon to be well done
Bake for a shorter duration if you like your salmon medium-done
The baking time will also depend on how thick your salmon fillet is, mine was about 1.5” thick in the thickest part
Serve warm with a salad, pasta, roasted vegetables, potato mash, etc
