01 -
Dump the salt, powdered sugar, cocoa powder, and flour into your food processor. Give it a quick blitz so it all looks the same.
02 -
Throw in your cold butter cubes and pulse it. It’ll look a bit like wet sand or chunky crumbs when it’s right.
03 -
Crack your egg and pour in the vanilla. Mix those, then, while pulsing, pour them slowly into your food processor. Don’t go wild, just until almost mixed.
04 -
Add a spoonful of ice water at a time, pulsing each time, until your dough barely sticks when you squish it.
05 -
Pat your dough into a thick circle, wrap it up in plastic, and stash it in the fridge for at least an hour. Overnight’s even better.
06 -
Get your oven warming to 175°C now.
07 -
Roll your chilled disk out on parchment. Make it big enough so it’ll fit your 23 cm tart pan evenly thick everywhere.
08 -
Move the dough to your tart pan, fit it into the edges, and snip off any parts hanging over.
09 -
Pop the tart pan in the freezer for 15 minutes. This’ll make the dough firm up nicely.
10 -
Put parchment on the cold dough and pile on pie weights or beans. Bake that for 20 minutes.
11 -
Pull out the weights and paper, then bake another 5 to 10 minutes. You want it set all through. Cool it off completely before filling.
12 -
Set your chopped chocolate in a big heat-safe bowl.
13 -
Heat the heavy cream in a sturdy saucepan on medium, just until it’s about to bubble gently. No boiling!
14 -
Pour the steamy cream straight onto your chocolate. Let it sit for 5 minutes so it melts down.
15 -
Stir until it’s all smooth and creamy. Add the soft butter, vanilla, and salt. Stir until shiny and smooth as silk.
16 -
Pour your set ganache into the cooled-off tart shell. Give the pan a gentle shake so any bubbles escape.
17 -
Let your tart hang out in the fridge for a good 4 hours or leave it overnight. You want it fully firm.
18 -
Bring the tart out about 15 or 20 minutes before slicing. Toss on berries, a dusting of cocoa, a dollop of cream, or a salty sprinkle if you’re feeling it.
