Instructions
The pastry dough
Place the flour, sugar, and salt in an electric mixer and mix 1 minute.

Wrap the disk in plastic wrap and place in the refrigerator.

In a sauce pan on medium, heat add the rhubarb, orange juice, and sugar.
Bring to a simmer and cook for 5 minutes.

Place in an oiled pie dish.
Pour the rhubarb into the pie dish. Set the sauce pan aside, but don't rinse.
Fold the edges of the pastry dough over the rhubarb.
The crumble topping
In the sauce pan that you cooked the rhubarb in, add the oats, flour, sugar, butter, and salt.
Mix the with your fingers until the butter is incorporated into the oats, flour, sugar, and salt.
Sprinkle the mixture randomly over the crostata.
Place in a 375° oven and bake for 30 minutes.
Let cool and serve with vanilla ice cream or whipped cream.
Notes
Rhubarb and blood orange season overlap for just a few weeks in spring and they complement each other perfectly.If you can't find blood orange, regular orange juice will work.
