Equipment

  • cutting board and sharp knife
  • measuring cup - 8oz. or more
  • small mixing bowl
  • small sauce pan
  • sauté pan
  • potato masher
  • mesh strainer
  • baking sheet with a rack - to toast baguette slices
  • paper towel - 1 sheet
  • tin foil

Ingredients

For the Reduction Sauce

  • 8 oz. concord grapes
  • 1 tbsp. balsamic vinegar
  • 1 tbsp. honey
  • ½ tsp. honey mustard
  • 1 tsp. rosemary - minced

For the Rest

  • ½ pound skirt steak
  • 1 pound Florette cheese
  • 1 tbsp. olive oil
  • 1 tsp. kosher salt
  • 1 tsp. fresh pepper
  • ½ tsp. onion powder
  • cardamom - just a pinch
  • champagne grapes - or sliced grapes for garnish
  • arugula - for garnish

Instructions

  • Mince 1 tsp. fresh rosemary and set aside. In a small sauce pan, add 8 oz. concord grapes, 1 tbsp. honey, and 1 tbsp. balsamic vinegar. 
  • Use a potato masher or fork to break up grapes in the sauce pan. Turn heat to MEDUIM-HIGH, and allow to boil and reduce for 7 minutes, stirring occasionally.
  • After 7 minutes, reduce heat to MEDIUM, add 1 tsp. of minced rosemary and ½ tsp. honey mustard. Stir, and allow to further reduce for 2 more minutes. Remove from heat.
  • Carefully push sauce through a mesh strainer, leaving only seeds, skins and rosemary. Place sauce in a sealed container until ready to assemble appetizers.
  • Preheat oven to 350 F. (175 C.) and thinly slice baguette into 18 pieces. Place slices on a baking sheet with a rack. When ready, place baguette slices in oven and toast for 7-10 minutes.
  • Use a paper towel to thoroughly dry both sides of ½ pound skirt steak. In a small bowl, mix 1 tsp. kosher salt, 1 tsp. fresh pepper, ½ tsp. onion powder and a pinch of cardamom. Thoroughly rub both sides of steak with spice mixture. 
  • Turn heat to HIGH under a sauté pan, and allow it to heat for 1 minute. Add 1 tbsp. olive oil to the pan and then the seasoned skirt steak. Allow it to sear for 3 minutes maximum - not a moment longer. Flip, and sear for just 2 minutes on the other side. Remove and allow it to rest under tin foil for 10 minutes. Then, slice into 18 pieces.
  • Apply a liberal amount of Florette cheese to each slice of baguette, add a slice of skirt steak, liberally swipe each piece of skirt stake with balsamic-grape reduction, top with champagne grapes and a single leaf of arugula

Notes

1. I suggest keeping the same cook time, even if your steak is thicker than mine:
I had a VERY thin skirt steak, just over half-an-inch thick. The steak came out just a little over-medium, so just expect that if you have a steak that’s closer to an inch thick, it will just be perfectly medium. Don’t increase cook time, or the edges may burn.
2. Make sure to mash your grapes before reducing.
Those grapes will POP when they get hot! So don’t skip the step to a potato masher or fork to break them up a bit before they get too hot.
3. If you can't find Florette cheese:
Substitute mild, very creamy cheeses. Don’t use one that’s herbed or includes truffle or other flavorings. You don’t want the cheese to overpower the steak and concord reduction. Here are some suggestions:
  • Triple Cream
  • Brie
  • Sheep’s brie
  • Taleggio
  • Teleme
  • Stracciatella
  • Burrata
  • Brebicet
  •  
4. If you can't find concord grapes:
Simply use easy-to-find purple grapes.
5. If you can't find champagne grapes:
Use an extra sharp knife to dice seedless grapes into tiny cubes! It looks almost as pretty!
