Prepare your grill for grilling with charcoal. While the charcoal is getting hot, shuck one dozen oysters. Shucking the oysters was the hardest part of this recipe. Get a good oyster knife and be careful. There are lots of tutorials for how to shuck oysters on the web. Try not to lose too much of the oyster juice as you are shucking. I relegated this job to my husband while I prepared the butter sauce.
Melt 2 sticks of butter and add a couple minced garlic, a tablespoon of finely chopped shallot, a dash of Worcestershire sauce, a bit of salt and pepper and a splash of hot sauce. Whisk these together.
When the coals are white hot, place the oysters, shell side down, directly on the grate. Let them cook until the juice just starts to bubble a bit.
Pour the melted butter mixture over each oyster (be careful here because when it spills over the fire will flare). Sprinkle a bit of Parmesan, Romano and Asiago cheese blend on each oyster and grill until the cheese is melted. The total cooking time for us was about 5 minutes.
Preheat oven to 450 degrees.
Bring water and butter to boil. Add the cup of flour all at once and mix it with a wooden spoon until the dough pulls away from the pan in a ball and forms a thin film in the pan. Remove the dough from the heat.
Add the blue cheese, Dijon mustard, pepper and herbs to the dough. Transfer dough to a mixing bowl and allow to cool for a few minutes. Beat the eggs into the mixture, one at a time, with an electric mixer, using the paddle attachment.
Place parchment paper on baking sheets. Scoop dough onto the baking sheets, one tablespoon at a time, using a tablespoon cookie dough scooper. puffs into oven and bake for about 10 to 15 minutes, turn heat down to 350 degrees and bake for another 10 minutes. Turn oven off and allow pastry to dry out until the oven is cool (another 10 to 20 minutes). Remove baking sheets from oven and enjoy! These also freeze well so you can make them ahead of time!
