Step 3 - Transfer the mashed potatoes onto a working surface. Dig a well in the middle and add the cooked Swiss Chard, 2 cups (256g) all-purpose flour, 1 tsp salt, nutmeg, black pepper and egg yolk. With your hands, mix and combine all the ingredients into a crumbly, sticky paste. Slowly sprinkle in extra flour (a little handful at a time) and mix it in until the dough comes together into a smooth ball that doesn’t stick to you fingers anymore.

Step 4 – Divide the dough in 4 equal pieces and roll each piece into a long log (about 1.5 inch/3.8cm thick). Using a large knife, slice the logs into 1.5-inch (3.8cm) pieces.

Step 5 – Bring a large pot of water to a boil with 1 tsp salt. Add some gnocchi (don’t cook all the gnocchi at once, work in several batches, at least 4) and cook until the gnocchi float to the surface of the water (this means they are ready). Immediately take the gnocchi out of the water (use a slotted spoon) and transfer them onto a large serving plate with 4 tbsp (60g) of butter. Cook all the gnocchi and stir to make sure the gnocchi are evenly coated in butter.
