For a tangier flavor, use dill pickle spears cut into smaller pieces instead of cornichons. Experiment with different cheeses! Gruyere, pepper jack, or even a smoked Gouda would be delicious. If you're short on time, pre-cooked bacon bits can be used, but freshly cooked bacon provides the best flavor. Ensure the cornichons are well-drained to prevent the dough from becoming soggy. These are best served warm, but can be reheated in the oven or microwave.
