Heat oven to 450°F and line a large sheet pan with parchment paper.
Bring a large pot of water to a boil and add 1 tsp salt. Add potatoes to water and boil for about 10 minutes, or until just tender.
Meanwhile, in a large bowl, whisk together oil, salt, garlic, chili, rosemary, onion powder, sugar, pepper and cayenne. When potatoes are boiled, gently scoop them into the bowl with a slotted spoon and toss well with the seasonings. Pour out onto the prepared sheet pan and bake until potatoes are cooked through and browned, 15-20 minutes, flipping once at the halfway mark.
Set a large pot over medium-high heat and add about 2-inches of vegetable oil. Follow the instructions on the back of the ORIGINAL BEER BATTER MIX bag to cook fish.
Plate potato wedges and fish and serve with your favourite coleslaw, ORIGINAL TARTAR SAUCE and lemon wedges.
