Preheat the broiler to high and place a foil-lined baking sheet or large cast-iron skillet under the broiler to heat.
Toss the shrimp with kosher salt and set aside.
In a small saucepan over medium-high heat, combine the non-alcoholic malt beverage (or chicken broth) and garlic.
Simmer until reduced to about 3 tablespoons and slightly syrupy, about 5 minutes.
Reduce the heat to low and add the butter one piece at a time, whisking continuously until smooth and emulsified.
Remove from the heat and stir in both the fresh harissa paste and dried harissa seasoning.
Pour the harissa butter sauce over the shrimp and toss until evenly coated.
Carefully spread the shrimp in a single layer on the hot baking sheet or skillet.
Broil for about 4 minutes, or until the shrimp are opaque and cooked through.
Serve the Quick Broiled Shrimp With Harissa Recipe immediately with crusty bread and fresh lemon wedges.
