Prepare cod by washing and drying each filet completely.
In a large skillet, heat 1 tablespoon butter over medium-high heat.
In a long bowl or plate, mix together almond flour, salt, and pepper. Dredge each piece of cod on both sides.
Add cod to skillet and cook for 2-3 minutes per side (longer for thicker pieces).
Once cooked on both sides, place cod filets on a clean plate.
Add remaining tablespoon of butter to pan, along with shallot and garlic. Cook for 1 minute.
Add in stock, lemon juice, and capers, and let cook for medium-high heat for 5 minutes until sauce has reduced.
Add cod filets back into skillet, reduce heat to medium, and spoon capers and sauce over top of each filet. Let heat through with sauce for a few minutes before serving.
Garnish with fresh parsley.
