In a medium skillet, cook bacon over medium heat until browned and crisp. Remove bacon using a slotted spoon, and let drain on paper towels, reserving drippings in skillet.
Melt butter with drippings over medium-high heat. Add chives, parsley, dill, and garlic; cook until tender, about 2 minutes. Remove from heat.
Preheat oven to 425°. Divide shortening among 4 (6-well) cast-iron corn stick pans. Place pans in oven to heat.
In a large bowl, whisk together cornmeal mix, buttermilk, mayonnaise, and egg; stir in bacon and garlic-herb mixture. Remove hot pans from oven, and divide batter among wells of pans.
Bake until golden brown, 15 to 20 minutes. Let cool in pans for 10 minutes; serve warm.
Notes
Kitchen Tip: You can also bake the cornbread in a 10-inch cast-iron skillet.
