Pistachio Dacquoise
Heat oven to 325°F / 165°C.
Line a sheet pan with parchment.
Sift together the ground pistachios, almond flour, and powdered sugar.
In a clean bowl, whip the egg whites with the salt to soft peaks.
Rain in the granulated sugar and continue whipping to a glossy medium-stiff meringue.
Fold the dry ingredients into the meringue gently, just until combined.
Spread into a thin even layer, about ¼ inch thick.
Bake 14–18 minutes until lightly golden and just set.
Cool completely, then cut into shape of your pan.
Chef notes (for a better dacquoise): Grind pistachios with a little of the powdered sugar to prevent turning into pistachio butter. Dacquoise is fragile when warm—cool fully before cutting. If it domes slightly, flip it over when fitting to the pan (flat side up = cleaner layers).
Prepare The Pan
Line a loaf pan with parchment paper, leaving overhang so the semifreddo can be lifted out easily.
Place the pan in the freezer while you prep.
Tip: A frozen pan helps the first layer set faster and keeps your swirls sharper.
Make The Date Caramel
Place dates in a bowl and cover with boiling water. Let soften 10 minutes.
Transfer the dates and 120 g of the soaking liquid to a blender.
Add butter, vanilla, lemon juice, and salt.
Blend until completely smooth and glossy. Texture should resemble thick caramel.
Cool completely before assembling.
Chef tip: Softening the dates prevents graininess (the standard technique for silky date caramel). If your dates are very dry: soak an extra 5 minutes before blending.
Make The Pate A Bombe (Egg Base)
Place egg yolks in the bowl of a stand mixer and begin whisking on medium.
In a small saucepan, combine 120 g sugar + 40 g water.
Heat syrup to 118°C / 244°F (soft-ball stage).
With mixer running, slowly stream the hot syrup into the yolks.
Continue whipping 5–7 minutes until the mixture is pale, thick, tripled in volume, and cool to the touch.
Chef notes: Pour syrup in a thin stream down the side of the bowl (not onto the whisk) to avoid splatter threads. If you don’t have a thermometer, you can still do it, but the texture is most consistent with one.
Add Yogurt Flavor
Gently whisk yogurt (or labneh), vanilla, lemon zest, and salt into the pâte à bombe until smooth.
Tip: Mix gently—this is where you protect the air you built.
Whip The Cream
In a separate bowl, whip the cold heavy cream to soft-medium peaks. It should hold shape but still look silky.
Warning: Overwhipped cream makes semifreddo grainy.
Fold The Mixture
Fold one third of the whipped cream into the yogurt base to lighten it. Then gently fold in the remaining cream until smooth and airy.
Cue: It should look like a light mousse.
Assemble
Cut dacquoise to fit your pan and place it as the bottom layer.
Spread one third of the semifreddo mixture into the lined pan.
Spoon ribbons of date caramel and sprinkle pistachios.
Repeat layers until used.
Use a knife to create gentle swirls—avoid overmixing.
Tip: If you want cleaner layers, chill the loaf 10 minutes between layers. Optional, but it keeps the caramel from sinking.
Freeze
Cover and freeze at least 8 hours or overnight until firm.
Serve
Let sit 5–7 minutes before slicing.
Lift out using parchment.
Slice and finish with: extra pistachios, date caramel, fresh sliced dates, chocolate drizzle, extra lemon zest
