Preheat the oven to 375F.
-
Rinse and sort through the berries, removing any stems (snipping off the tops and tails of the gooseberries with a pair of scissors) and place all of them in a medium bowl.
-
Place the honey in a small sauce pan and warm over medium heat to a gentle bubble.
-
Add the rosewater and the saffron and stir until softened and fragrant. Set aside to cool for about 10 minutes.
-
To the bowl of berries, add the honey, the lemon juice and the cornstarch or arrowroot starch and stir to combine well.
-
Open the packaging of puff pastry and lay out (either in the parchment paper it came in, or if there is none, then onto a fresh piece of parchment paper. Roll out to a rough 10 inch (26cm) circle (don't worry too much about shape). In my case, the puff pastry is practically at this size to begin with, so I just place the entire sheet (sitting on the parchment) onto my baking sheet.
-
Trim away the corners on a 45 degree angle, so that you won't have excess pastry in those spots when folding the pastry over the filling.
-
Mound the berry filling onto the pastry, leaving a good 1 inch border. (the border can be slightly larger (1 1/4 inch, if you like)
-
Gently fold the edges up and over the berry filling, pleating as you go around. Press gently to get the folds to stay.
-
Brush the entire border with the egg wash. Sprinkle the pastry with turbinado sugar.
-
Take the almond slices and sprinkle the edges with them, pressing them in very gently where needed.
-
Place the baking sheet on the middle rack in the oven and bake until the juices are bubbling and the edges are golden brown. This should take between 25-35 minutes. But each oven is different.
-
Remove the baking sheet to a cooling rack. Once cooled a bit, use the parchment to remove the crostata to the cooling rack itself.
-
You will want a really good sharp serrated knife to cut through the almonds and pastry.
-
Serve with vanilla ice cream.
