What You Need
130g sugar
40g light corn syrup
81g heavy cream at room temperature
1 teaspoon vanilla extract
1/4 teaspoon kosher salt
pate sucree dough
510g blackberries, rinsed and dried thoroughly
1 teaspoon (about 3g) unflavored gelatin powder
What To Do
Roll out your pie dough and cover up your 9-inch removable tart pan, lining it up to form a crust. Claire suggest having extra dough saved in case there are any cracks in the crust so you can fill it in. Once you’ve done this, chill the dough crust. Bake the crust covered in foil and then uncovered for about 30 to 40 minutes until you reach a deep golden brown.
Allow the crust to completely cool, and make the blackberry filling in the meantime. Combine your sugar, light corn syrup, and water and let it boil down until it reaches a light medium amber color. Be careful not to let it burn, so keep an eye on it. At this point, you want to add in the heavy cream, vanilla, salt, and blackberries and cook for about 5 minutes. The blackberries should break down and it will smell incredible.
As your caramel cools, arrange the blackberries in your pie crust. Once the caramel has fully cooled, strain it to get any solids out and then mix in the liquified gelatin powder. Place it over an ice bath and sit until it has reached a consistency that resembles heavy cream.
After it has cooled and reached the correct consistency, pour it into the crust with the blackberries. Make sure it is evenly poured around the berries. After this, put it in the fridge to chill for 2 hours minimum.
Take it out and enjoy a slice of this gorgeous tart!
