If you half time, boil potatoes in their jackets, then peel and mash, I didn't, so peel, chop and boil until cooked. Mash and while still warm, dust a large surface with semolina flour and knead in the flour

Make a well and add the egg and a pinch of salt. Knead until combined but try not to over work it. Use more semolina flour if needed to roll up, cut and shape into a sausage as shown in the picture

Using a sharp knife, make your gnocchi no bigger than a centimeter (they swell during cooking). Set a side covering with a clean tea towel. Bring a pot of lightly (gnocchi already salted) salted water to the boil. Cooked shallot gently in olive oil until soft. Add diced courgette

After 2-3 mins, add the speck and saffron. Stir well. Add a ladle of water from the now boiling pot. Carefully drop the gnocchi in the boiling water. When they rise, minute or two, max, transfer to sauce using a slotted spoon

Add another ladle of cooking water if needed. Mix well and serve with Parmesan
