Fried Dill Pickles

1 cup flour
1/4 cup cornstarch
1 tsp baking powder
1/4 tsp salt
1 cup ice water
1 egg yolk
2 Tbsp dill pickle juice
8 dill pickles, sliced 1/4" thick or 4 cups dill pickle slices, drained
oil for frying

Stir flour, cornstarch, baking powder, and salt into a large bowl. Make a well in center; add water, egg yolk, and pickle juice, all at once. Stir with wire whisk to make a smooth batter. Cover bowl and refrigerate 30 minutes. Heat at least 2 inches of oil in deep fryer or large saucepan to 375 degrees F. In batches, dip pickle slices in the batter to coat evenly and lightly. Fry without crowding in hot oil until golden brown and crisp, 1 1/2 to 2 minutes. Drain on paper towel and serve at once. Dip in a sauce if preferred. Makes about 8 servings as an appetizer or side dish.
