In a medium pot, bring water to a boil. Add the cubed potatoes and cook for 10-15mins on medium heat. Drain the potato and transfer to a large bowl.
Mash the potato in the large bowl using a thick rolling pin or a fork. Add the flour, salt and turmeric. Mix to combine. The dough will be very coarse and crumbly.
Drizzle in the olive oil and mix until a ball of dough is formed. Using your hands, knead the dough in the bowl until there are no traces of flour.
Flour a clean surface such as a large cutting board or a table and transfer the dough onto the surface.
Working with half of the dough at a time, roll out the dough evenly until it is about 1 inch thick. Using a paring knife, cut the rolled out dough into 1 inch pieces.
To make the traditional gnocchi shape, take 1 piece of cut dough and roll it down the backside of a fork. Place on a lightly floured plate. Repeat with all the pieces of dough.
Repeat steps 4 and 5 with the other half of the dough.
To cook the gnocchi: bring a pot filled about ⅔ of the way with water to a boil and add 1 tsp of oil and a pinch of salt. Add the gnocchi and cook on medium-high for 10mins. If you want softer gnocchi, add another 2-3mins. Save ¼ cup pasta water.
Drain the gnocchi and transfer into a bowl or pan to toss with your favourite sauce and mix in the pasta water. Serve :)
