In a large bowl, mix together 1 1/2 cups self-rising cornmeal, 1/2 cup all-purpose flour, 1 tsp salt, 1/2 tsp black pepper, and 1 tsp garlic powder. Combine these dry ingredients thoroughly to ensure even distribution of flavors.
Add in the 4 cups coarsely chopped dill pickles and 1/2 sweet onion (finely diced). Toss to ensure that the pickles and onions are well-coated with the dry mixture.
In a separate bowl, beat together 1 large egg and 1/2 cup buttermilk until well mixed. Pour the wet mixture into the bowl with the pickles and flour mix. Stir until all ingredients are fully combined and the batter is formed.
Heat the oil in a deep skillet or frying pan to a temperature of about 350°F. It is crucial to maintain this temperature for optimal frying results.
Using a tablespoon, drop heaping spoonfuls of the batter into the hot oil. Fry them for approximately 4-5 minutes on one side until they are golden brown. Carefully flip each fritter, pressing them flat gently with a spatula.
Continue cooking until they are crispy and golden on both sides. Remove fritters from the oil and let them drain on paper towels to absorb any excess oil.
Serve the fried pickle fritters while they are hot, alongside your favorite dipping sauces like ranch dressing or a spicy aioli!
