Lavender, Lemon & Honey Semifreddo Cake

🧂 Ingredients

• 3 large eggs

  at room temperature
• 1/4 cup granulated sugar

  (60 g)
• 1/2 tsp vanilla extract
• pinch salt
• 1/2 cup all-purpose flour

  (70 g) or cake flour, plus a little for dusting
• butter

  for greasing the pans
• 1/2 cup sugar
• 1/2 cup water
• 1/4 tsp lavender
• 1/4 cup lemon juice
• 1 cup cream
• 1/2 tsp lavender
• 1 tsp sugar

  (optional - see instructions)
• 4 large eggs

  at room temperature
• 2 tbsp lemon zest

  (approx 2 lemons)
• 1/4 cup lemon juice
• 1/2 cup honey

  or 1/2 cup + 1 tbsp sugar
• 1/8 tsp salt

Instructions

• 1 Line two 8 inch cake pans with a circle of parchment paper.  Grease the sides
  and paper with a bit of butter, and dust with flour.
• 2 Preheat your oven to 350°F (176°C), and position the racks so that the cakes
  will sit in the middle.
• 3 Note: these instructions are for a stand mixer.  If you're using a hand mixer,
  see the notes below for the variation.
  
  In an electric stand mixer with a whisk attachment, beat the eggs at high speed
  for about 1 minute, then add the sugar slowly.  Add the vanilla and salt. 
  Continue to whip at high speed for 5 minutes.  The resulting mixture should be
  airy, light yellow, and have the sugar well-dissolved.  If you see a lot of
  grains of sugar, or the mixture isn't looking very airy, continue to whip for
  another 2-3 minutes.
• 4 Sift the flour into the egg and sugar mixture slowly, stirring gently with a
  spatula to combine without deflating the whipped eggs.  Stir just enough to
  incorporate the flour into the batter, taking care to get the spatula to the
  bottom and edges of the bowl to avoid leaving any clumps.
• 5 Divide the cake batter between the two pans.  Bake in the center of the oven for
  approximately 20 minutes, or until the top is golden and a toothpick emerges
  clean.  Carefully remove the cakes from their pans, before transferring them to
  a rack to cool.  You can keep one of the parchment paper rounds to re-line the
  pan for the freezer step (see below). When cooled, finish with lavender-lemon
  syrup (see next step).
• 6 Combine the sugar, water, lemon juice, and lavender in a small saucepan.  Heat
  over low on the stove top, keeping the mixture just below a simmer for about 5
  minutes.  Set aside to cool for at least 10 minutes (note that you can also make
  and refrigerate the syrup ahead of time).
• 7 Whip the cream until it forms stiff peaks, then set aside. Clean and dry the
  mixer bowl.  Note that this step can be done day the day before to save time.
• 8 Optional - Place the lavender and sugar together in a spice grinder or mortar,
  and grind together to make a fine lavender/sugar powder, then set aside.  You
  can sift out any larger pieces with small strainer.  If you don't mind whole
  lavender flowers in the semifreddo then you can skip this step and omit the
  extra tablespoon of sugar.
• 9 Set up double boiler on the stove.  I simply float the stand mixer bowl in a
  large pot (Dutch oven) filled 2/3rds of the way with water, but anything large
  enough to easily accommodate your bowl.  Heat the water but keep well below a
  boil.
• 10 Add eggs, honey, lemon juice, zest, lavender/sugar, and salt to the clean and
  dry stand mixer bowl, or another large metal bowl if your mixer bowl won't sit
  comfortably on a double boiler.  Mix together.
• 11 Place the bowl on the double boiler.  Gently whisk the ingredients to keep them
  moving (this will keep the egg from scrambling).  Cook until the temperature of
  the mixture reaches 165°F (74°C) - about 5-7 minutes.  It should look thick and
  glossy, but still be quite runny.
• 12 Transfer the mixture to the stand mixer and whip with the whisk attachment until
  the mixture is airy and approximately quadrupled in size (about 5 minutes, but
  this will vary a bit depending on your mixer, and take longer if you're using a
  hand mixer).
• 13 Gently fold the whipped cream into the mixture with a whisk or a spatula.  Mix
  just enough to incorporate all the ingredients while taking care not to deflate
  things.
• 14 Place one of the parchment paper rounds back into a cake pan.  Take a long (26
  inch/66 cm minimum) sheet of aluminum foil and fold it in half the long way,
  then shape it into a round wall lining the cake pan.  This will act to extend
  the walls of the cake pan upward, allowing you to make the semifreddo cake
  taller.  Gently slide one cake into the pan (doing this last will help to hold
  the foil in place).
• 15 Brush about 1/3 of the syrup over the cake in the pan.  Set the remainder aside.
• 16 Pour the finished semifreddo over the bottom cake layer.  Tap gently to remove
  any air pockets.
• 17 Gently place the second cake over the semifreddo.  Brush the top of this cake
  layer with another 1/3 of the syrup.  Transfer the cake to the freezer and
  freeze for at least 8 hours.
• 18 Remove the cake from the freezer and gently pull out the aluminum foil lining. 
  Lift or turn the cake out of the pan carefully (it may help to let it thaw for a
  minute or two if the semifreddo is frozen to the pan.  Remove the parchment
  paper lining.
• 19 Allow the cake to sit for about 3-4 minutes to soften a little.  Garnish with
  lavender flowers or a dusting of powdered sugar. Slice with a large, thin knife
  that's been dipped in warm water.
• 20 Optional: take the remaining lemon/lavender glaze and mix it with 1 tbsp of
  honey.  This is a bit easier to do if you heat the honey first (10 seconds in
  the microwave should do it).  This can be drizzled over the cake, or on
  individual slices.
