Step 1:
Bake the sweet potatoes in the oven at 200 °C/390 F. Depending on the size this can take between 45 minutes to 1.5 hours.
Step 2:
Once your sweet potatoes are soft all the way through (you can test that by poking a small sharp knife inside) take them out of the oven, cut in half and let them steam for a moment to dry out a bit.
Step 3:
Place the passe-vite on top of a bowl, scoop out the soft inside of the sweet potatoes and pass them through the passe-vite.
Step 4:
Weigh out the sweet potato puree. For one kilo of sweet potato puree add 300 g of flour/ 10.6 ounces, two egg yolks and a pinch of salt.
Step 5:
Mix all the ingredients together until they are combined into a dough.
Step 6:
Dust your working table with some flour. Take about a handful of dough at a time and roll it into a sausage with a diameter of about 2 cm/ 0.75 inch.
Step 7:
Use a dough scraper to cut the roll into pieces between 1 and 2 cm (1/2 inch). Dust the gnocchi lightly with a bit of flour and set them aside. In the meantime, bring a big pot with salted water to a boil.
Step 8:
Once all your gnocchi are shaped you can cook them in small batches in heavily salted boiling water. Make sure to not boil to many at the same time as they will stick to each other. You know the gnocchi are done when they start floating at the surface.
Step 9:
Take the gnocchi out with a skimmer and put them in an extra bowl. It’s best to mix them immediately with some olive oil to prevent them from forming a big block.
Step 10:
If you would like your gnocchi to be fried, simply fry them in some olive oil in a pan until golden brown.
Step 11:
Now fry off the gnocchi in some olive oil in a pan until golden brown. with two cloves of garlic sliced into slivers.
Step 12:
Add the basil oil onto a clean deep plate and gently place your gnocchi on top. Now decorate by adding chunks of feta, 3 dollops of the basil spread and sprinkle on walnuts, black pepper and some fresh basil. Voila, bon appetite!
