Heat the oven to 400 degrees.
Line a 9 inch pie plate with the pastry. Build up the sides of the pastry on the rim so the custard does not over-flow. Crimp or flute the edges.
Cover the bottom of the pastry with a round of parchment paper and add enough dried beans, peas or rice to partly fill the shell. Bake for 10 minutes.
Reduce oven temp to 375 degrees. Remove and discard the beans and parchment paper and set the pastry-lined pie plate aside.
Cook the bacon until crisp and remove it from the skillet. Pour off all but 1 Tbsp. of the fat remaining in the skillet. Cook the shallots/scallions in the remaining bacon fat until they are just transparent.
Combine the eggs. Add cream, nutmeg, salt, pepper and Tabasco sauce. Crumble the bacon and sprinkle one half of the bacon into the shell, add shallots/scallions and cheeses. Top with the second half of bacon crumbles.
Slide the pie plate onto a baking sheet. Strain the custard mixture into the shell.
Bake the pie until a knife inserted 1 inch from the pastry edge comes out clean, about 50-55 minutes. Remove to a wire rack. Let stand for 5-10 minutes before serving.
