Did a gluten-free adaptation with Bob’s Red Mill All-Purpose Flour blend (red bag), added 1/4 tsp baking soda more than the recipe called for, and substituted seltzer water for regular water. The batter was thin, but worked well on previously frozen, patted-dry rock fish. My picky-eater inhaled it. The husband and I wanted more seasoning, so I will add paprika, garlic powder, and celery salt next time.
