Preheat the oven to 200 degrees Celsius.
Make small wholes in the sweet potatoes to avoid them from exploding in the oven.
Place on a parchment covered baking pan and bake in the oven for 40-50 minutes, until soft all the way through. Take out of the oven and let them cool for a few minutes.
Peel the sweet potatoes and mix them using a hand mixer until you have a smooth potato mash.
Add two dl of mashed sweet potatoes to a bowl together with the ricotta and mix to combine.
Next add the salt and gluten free all purpose flour. Mix again until you have a firm dough. The dough will be a little sticky, but you should still be able to roll it into long stripes on a floured board.
Roll the dough into long stripes, preferably about 2 cm thick.
Cut the into equally sized pieces (preferably the width of a fork) and gently press down a form to make a form mark (optional, this is not a must). Repeat with the remaining pieces.
Bring water to a boil in a pot with some salt in it.
Lower the heat and let the water simmer.
Add 5-6 pieces of gnocchi to the water if using a smaller pot, or 10-12 using a bigger one. The gnocchi are ready when they float up to the surface.
Take them out of the water and drain well. Place on a plate, but make sure they don't tough each other to avoid them from sticking together. Repeat with the remaining gnocchi.
Meanwhile prepare the burrata, tomatoes, olives, sun-dried tomatoes and pistachio nuts.
Divide one burrata and place at the bottom of two bowls. Add gnocchi on top. Top with the other burrata, tomatoes, olives, sun-dried tomatoes, chopped pistachio nuts and fresh basil.
