Begin by gathering and prepping all of your spicy garlic-lime sauce ingredients according to the ingredient list above to have ready and organized for use.
To prepare the sauce, place all ingredients into a food processor and processing until smooth and well blended. Pour into a bowl, or into a squeeze bottle, ideally, and keep chilled until ready to use.
Next, gather and prep all of your citrus slaw ingredients according to the ingredient list above to have ready and organized for use.
To prepare your citrus slaw dressing, whisk together the orange zest, orange juice, lime juice, pinch of salt and pepper, agave or honey, and oil until well-combined (you can also shake these vigorously in a small mason jar for convenience), and set aside for a moment.
Add both of your shredded cabbages and the cilantro into a medium-size bowl, and toss the dressing with the cabbage/cilantro mixture. Keep chilled until ready to use.
Next, gather and prep all of your fish taco ingredients according to the ingredient list above to have ready and organized for use.
To prepare you fish tacos, add your cod pieces to a bowl and season with a couple of pinches of salt and pepper, plus the cayenne, cumin, coriander and garlic powder. Allow them to marinate for a few minutes while you get your oil ready and prepare to fry.
Prepare a baking sheet with foil and a place a wire rack over top to hold the cod once it's been fried.
Next, add enough oil to a deep pan or a medium-size pot so that the fish can be submerged when you fry it (about 3 to 4 cups worth), and bring it to 365°.
While your oil heats, whisk together the flour with a couple of pinches of salt and pepper, and slowly pour in the beer and whisk just until smooth.
Once the oil is hot, dip the pieces of cod into the batter and fry in batches for a 3-4 minutes, or until golden-brown.
To assemble the Baja fish tacos, add a couple of pieces of the fried cod to the bottom of a couple of corn tortillas, top with a generous amount of the slaw, add in some radishes (if using), drizzle the spicy garlic-lime sauce liberally over top, and finish with some extra cilantro and a squeeze of lime.
