Position a rack in the middle of the oven. Preheat oven to 375°F | 190°C. Line a baking tray / sheet with a large piece of foil, big enough to fold over and seal to create a packet (or 2 long pieces of foil over lapping each other lengthways to create your salmon packet, depending on the width of you fillet).
In a small saucepan, combine the honey, mustards, butter, garlic and lemon. Whisk until the honey has melted through the butter and the mixture is well combined.
Place the salmon onto lined baking tray | sheet. Pour the butter/honey mixture over the salmon, and using a pastry brush or spoon, spread evenly over the salmon. Sprinkle with a good amount of salt (about 2 teaspoons) and cracked pepper. Fold the sides of the foil over the salmon to cover and completely seal the packet closed so the butter does not leak.
Bake until cooked through (about 10-12 minutes, depending on the thickness of your fish and your preference of doneness). Open the foil, being careful of any escaping steam, and grill / broil under the grill / broiler for 3-4 minutes on medium heat to caramelise the top. Garnish with parsley and serve immediately with lemon wedges.
Notes
*If you don't want the addition of spice, leave it out all together OR add mild or sweet paprika for an added pop of colour.
