BLENDER COOKIES RECIPES

Steps:

• Preheat oven to 400 degrees F. 
• Take the beef tenderloin and drizzle with olive oil. Season well all over with plenty of kosher salt and freshly ground black pepper all over. Make sure it is at room temperature before cooking. Place a large cast iron skillet over medium-high heat on the stove top and sear tenderloin all over. Place the whole pan in the oven and roast the tenderloin for 15-17 minutes (depending on how thick your tenderloin is). An instant-read thermometer when inserted into the thickest part of the meat should read 130 degrees F for medium-rare. If you want it medium, cook for a further 3 minutes in the oven. Remove from the oven and tent with foil while you let it rest for 10 minutes before cutting.
• Make the bearnaise reduction first. In a small saucepan, combine half of the tarragon, shallots, vinegar and wine over medium-high heat. Bring to a simmer and cook until reduced by half. Remove from heat and set aside to cool. 
• Blend yolks and bearnaise reduction together in a blender. With the blender running, add 1/3 of the butter in a slow steady stream. Once it emulsifies, turn the blender speed up to high and add the remaining butter. Add the remaining half bunch of fresh tarragon leaves, season with salt and pepper and give it 1 more buzz. Set aside in a warm spot to hold the sauce.

Steps:

• In a large bowl, or in a stand mixer on medium speed, whip the heavy cream to glossy, medium peaks, about 5 minutes. Set aside in the fridge. In a small saucepan over gentle heat, melt the sugar with 1/4 cup water until dissolved. As soon as the syrup begins to boil, turn off the heat.
• Add chocolate and eggs to a blender. Blend on medium-high speed while slowly pouring in the hot sugar syrup, which will melt the chocolate and cook the eggs. Keep the machine running until the mixture is extremely smooth, then stream in the espresso, rum, vanilla and salt. Keep blending until the mixture has cooled to room temperature, about 1 minute, pausing to scrape the sides as needed.
• Fold 1 cup of the chocolate mixture into the chilled whipped cream until smooth, then add the rest of the chocolate mixture to the cream mixture and fold until there are no streaks. Pour into individual bowls, ramekins or glasses, and set in the fridge until firm, at least 2 hours or up to 24 hours. Serve chilled.
