Preheat oven to 425 degrees F.
Place the pie crust into a deep dish pie plate. Fold edges over and crimp.
Line pie shell with foil and fill with pastry weights or dried beans.
Bake for 20 minutes at 425 degrees F..
Remove from oven and cool about 30 minutes.
Reduce oven temperature to 375 degrees F.
Slice tomatoes and place in single layer on paper towels. Sprinkle with 1 teaspoon salt if desired. (This helps take some of the moisture out of the tomatoes, and in my opinion, is much preferable to seeding the tomatoes to get rid of the juice.)
Meanwhile, blend together mayonnaise, pepper, Old St Augustine Datil Zest Spice Blend, Old St Augustine Jalapeño Onion Relish, lemon juice and 3/4 cup of the parmesan or asiago cheese.
Blot tomatoes dry with paper towels, and place single layer of overlapping tomatoes on the bottom of the pie crust.
Place 1/2 of the corn on top of tomatoes and sprinkle with 1 Tbsp basil leaves.
Repeat with another layer of tomatoes and corn and 1 Tbsp basil.
Spread the mayonnaise mixture evenly on top.
Arrange one more layer of tomatoes on top of mayonnaise and sprinkle with the remaining cheese.
Top with additional 1/2 Tbsp basil leaves if desired, or you may reserve them for garnish just before serving.
Bake for 1 hour at 375 degrees F.
Use foil to cover edges of pie crust to prevent over browning.
Remove from the oven and let rest for 15 to 20 minutes before cutting into slices.
This may be served warm or at room temperature.
