Mad Men continued AMC's hot streak of well-acted, well-written, morally irreverent dramas with its sordid look at the lives of Madison Avenue's top advertisers. In an early episode, Roger Sterling attempts to woo America's favorite mistress with a light room service lunch: Oysters Rockefeller, Beef Wellington, and Napoleons. This week, blatantly disregard your cholesterol levels and fire up a Lucky Strike as we indulge in some hotel-room-hedonism with our silver fox boss.

Ingredients

For the puff pastry:

• 2 cups all purpose flour and several extra Tbsp for dusting
• A few pinches of kosher salt
• 1 cup ice water
• 2 sticks unsalted butter

For the beef tenderloin:

• 1 beef tenderloin
• ¼ pound prosciutto
• 3 Tbsp English Mustard
• Salt and pepper

For the mushroom duxelles:

• 10 mushrooms (chopped in food processor)
• 1 clove freshly crushed garlic
• 1 Tbsp thyme
• 2 Tbsp butter
• Cognac
• Heavy cream
• Salt and pepper

Method: Beef Wellington 

For the puff pastry:

1. Place all purpose flour on cutting board. Create trench within the flour mound and pour in a few tablespoons of the ice water. Carefully combine the ice water and flour. Then, reform the trench and begin the process again. Once the flour combination becomes chunky, use a bench scraper to help combine the water and flour. Repeat and keep mixing the water and flour until a dough that holds its shape forms. Form the dough into a square, wrap in plastic wrap, and place in the fridge. Chill for 30 minutes.
2. Cube the sticks of butter and place in the middle of a floured cutting board, then sprinkle flour on top. Taking a floured rolling pin, pound the butter together into one mass. Keep re-flouring the rolling pin and work surface. Keep pounding the butter until it is pliable and can be folded. Then, form the butter into a square, wrap with plastic wrap, and place in fridge for 10 minutes.
3. Generously flour your work surface, take the dough out of the fridge and start rolling out your sticky lean dough into a 12x12 inch square. Then, pound your butter square out so it is approximately a 6x6 inch square.
4. Place the butter square in the middle of the dough square and fold the edges of the dough square so they meet in the middle. Seal the edges of the dough square and roll out the square. Roll the dough out to a 12-inch long and 5-inch wide rectangle.
5. Fold the rectangle into thirds, like a letter, and then rotate it 90 degrees. Roll out again and repeat once more. Then, fold the dough back into thirds, wrap with plastic wrap, and place the dough into the fridge for 30 minutes. This allows the glutens to relax. Watch the video above to see this process!
6. After 30 minutes has passed, pull the dough out of the fridge and roll out. Fold into thirds and roll once more. Repeat this once more and then fold into thirds, wrap in plastic wrap, and place in the fridge for 30 minutes. Repeat this whole rolling process once more to create 6 total folds and 720 layers of butter. Again, watch the video to see this in action!
7. Fold into thirds and wrap in plastic wrap. Place the dough in the fridge for at least one hour and up to 24 hours. Next, begin preparing the beef tenderloin and mushroom duxelles.

For The mushroom duxelles:

1. In a food processor, pulse the mushrooms until finely chopped. Then, finely chop the thyme.
2. Over medium heat, melt butter in a skillet. Add mushrooms and combine with butter. Add thyme. Using a garlic crusher, crush garlic and add to mushroom mixture. Continue to combine over medium heat for about 10-15 minutes or until the mushrooms are caramelized.
3. Once the mushrooms are caramelized, add a generous splash of Cognac and stir to deglaze the pan. Add heavy cream and cook for several minutes or until all the moisture is gone. You should be left with a paté-like mixture. Set aside.

For the beef wellington:

1. Season the tenderloin liberally with salt and pepper. Leave kitchen string on tenderloin.
2. Place tenderloin into a ripping hot cast iron skillet. Sear on all sides and set aside. 
3. Lay down a large layer of plastic wrap that can wrap around the circumference and length of the tenderloin.
4. Lay prosciutto on top of plastic wrap so that it overlaps each piece like roof shingling. There should be about 2 rows with 7 strips of prosciutto in each.
5. Grab your tenderloin, cut off any kitchen string and brush tenderloin with English mustard.
6. Spread an even layer of the mushroom duxelles on the prosciutto. Place the roast at the end of the prosciutto and duxelles wrapping. Use the plastic wrap to leverage the wrapping around the roast. Twist the ends of the plastic wrap to seal. Place in the fridge to firm up. Again, watch the video to see this done!
7. Preheat oven to 450℉.
8. Generously flour your work surface before rolling out your puff pastry. Your puff pastry should be 3 inches wider than your roast and 12 inches longer.
9. Place plastic wrap on your work surface and place the dough on top. Grab your tenderloin from the fridge and unwrap. Place the tenderloin at the edge of the dough square.
10. Using the plastic wrap, roll the dough around the tenderloin and fold the edges down. Wrap the plastic wrap around the roast and then use Gordon Ramsay's Whipsy Flipsy method to seal the edges. Watch the video! Put it in the fridge for 20 minutes to firm up.
11. After firmed up, unwrap from plastic and place on a parchment paper-covered baking sheet. Brush the roast down with a beaten egg and use the back of a paring knife to decoratively score the dough. Sprinkle with flaky kosher salt.
12. Insert a temperature probe into the thickest part of the roast. Bake at 450℉ until the roast registers as 120℉ internally. Let rest for 15 minutes and then slice open to reveal the fruits of your labor.

Ingredients

• 1 sheet of puff pastry

For Custard (aka Creme Patisserie):

• 4 egg yolks
• ½ cup cornstarch
• 2 cups milk
• ½ cup sugar
• 2 tsp vanilla paste (or vanilla extract)
• 2 Tbsp crumbled butter

For decorative icing:

• 1 cup powder sugar
• 2 tsp corn syrup
• 2 Tbsp whole milk
• 2 Tbsp of melted butter
• Melted chocolate or cocoa powder

Method: Napoleon Cakes

For Custard (aka Creme Patisserie):

1. In a mixing bowl, whisk together the eggs and cornstarch into a light, ribbony mixture.
2. In a large saucepan, combine milk, sugar, and vanilla paste. Whisk together and bring to a bare simmer.
3. 1/2 cup at a time, add the milk mixture very slowly into the egg mixture. Be careful not to cook the eggs. Whisk continuously while doing this. After half the milk is added, you may dump the rest of the milk mixture into the egg mixture. Combine completely and return to the saucepan.
4. Over medium heat, whisk constantly until a thick custard forms. Kill the heat and add crumbled butter. Whisk in the butter until it is completely melted.
5. Pour custard into metal bowl and cover with plastic wrap. Make sure to press the plastic wrap down onto the surface of the custard. Place in the fridge.

For Decorative Icing:

1. In a bowl, whisk together sugar, corn syrup, milk, and butter.
2. Set aside a few tablespoons in another bowl. Add molten chocolate or cocoa powder to this icing.

For cakes:

1. Preheat oven to 450℉.
2. Take puff pastry and cut into 3 equal pieces. Bake for about 6 minutes at 450℉ or until light and fluffy. Remove from the oven and place another baking sheet on top of the pastry to weigh it down. Put the pastry back in the oven for an additional 4-5 minutes or until thin and crisp. Allow to cool completely.
3. Take creme patisserie (aka custard) and spread on top of one of the pastry squares. Place another pastry square on top and spread more custard.
4. Taking the final pastry square, spread the plain icing on top. Use an offset spatula to smooth.
5. Using a drinking glass to hold a pastry bag with a small round tip, spoon the chocolate icing into the bag.
6. Pipe chocolate icing onto top layer in long, straight lines across the length of the pastry. Drag the tip of a toothpick back and forth across the top of the icing, creating a decorative flair.
7. Place the remaining layer on top of the other layers. Plate up on a nice serving plate and hack yourself off a piece.
