Yes you can use this recipe to make a large tart or 2 small to medium sized tarts. The process is pretty much the same, but you will have to spread the filling with a small offset spatula. You might also need more strawberries to garnish the top. For garnishing a large tart, I recommend starting with a row of quartered strawberries all around the tart. Then making multiple small rosettes of cream in the middle of the tart to cover the confit,  and then placing the leftover quartered strawberries randomly in between the rosettes.
