How to Make It
Preheat the oven to 400°. In a blender, combine 1/3 cup of the olive oil with the garlic, crushed red pepper and 1 tablespoon each of the parsley and mint; puree until smooth. Season the garlic oil generously with salt.
Brush the baguette slices with the garlic oil; arrange on a large rimmed baking sheet. Bake for about 10 minutes, until crisp on the outside but soft in the middle.
In a medium bowl, mix the salmon with the remaining 2 tablespoons of olive oil and 1/3 cup each of chopped parsley and mint. Season the tartare with salt and mound on the toasts. Transfer to a platter. Drizzle mustard oil over the tartare and serve.
