Next, we are going to make our spicy and juicy crust. Cut the garlic into small pieces or crush it with a garlic press. Combine garlic, harissa paste (or tomato paste, or a mix of both to your liking) to a small mixing bowl. Add the lemon and salt and mix well. Spread the mix evenly on the salmon and transfer the pan into the oven to bake for 15 to 20 minutes.
