Prepare the Crust
Preheat oven to 350°F (175°C). Lightly grease a 9-inch tart pan with removable bottom.
In a bowl, mix flour, powdered sugar, and salt.
Cut in butter until crumbly.
Press mixture evenly into the tart pan.
Bake for 12–15 minutes, until lightly golden. Cool slightly.
Make the Pistachio Filling
In a bowl, mix ground pistachios, sugar, egg, cream, vanilla, almond extract (if using), and salt until smooth.
Assemble & Bake
Spread pistachio filling evenly into the warm crust.
Bake for 18–22 minutes, until just set in the center.
Cool completely at room temperature.
Finish the Tart
Arrange sliced strawberries on top in a circular or fan pattern.
Brush lightly with warmed jam or honey if desired.
Chill 30–60 minutes before slicing.
