You do not rinse gnocchi after cooking and instead you should drain them and then transfer them immediately to the sauce or a warm serving dish.
Rinsing the gnocchi with cold water can make the gnocchi lose their starch, which helps them stick to the sauce and can also result in a clumpy or unappealing texture, however it might be used in some certain cold preparations, such as salad.
For best results you can also toss the gnocchi with a bit of the pasta cooking water, which can keep them from sticking and help the sauce emulsify.
The potatoes that are best for gnocchi are Russet potatoes or even Yukon potatoes which are floury or starchy potatoes.
When making gnocchi you want to avoid high moisture new potatoes as the goal when making gnocchi is to achieve a light, fluffy and non gluey texture by minimizing the water content through baking instead of boiling.
The potatoes that are good for roasting or baking and potatoes with yellow or mealy flesh are also great potatoes for making gnocchi.
The amount of pieces of gnocchi per person is around 20 gnocchi per person or around 100g which is suitable for a starter.
A good general portion per person of gnocchi is between 100 to 130 grams of gnocchi per person.
Although the exact amount of gnocchi per person will also depend on if it's a main dish or a starter dish and even the appetite of the people eating the gnocchi.
And how hearty the sauce is also factors into the amount of gnocchi per person.
A serving of 6 oz to 9 oz of 170 to 255g of fresh gnocchi is often good for a main course.
Although for a smaller course or portion, then 20 gnocchi per person which is around 100g is often perfect for a starter.
As a main course it's best to have around 130 grams on the higher end for the recommended portion.
For a starter dish or side dish then the smaller serving such as 6 oz or 170g of fresh gnocchi, or around 20 pieces of gnocchi is often suitable.
Gnocchi is also often served with sauces, so you should also consider how filling the sauce is gonna be as a very rich sauce can allow for a smaller gnocchi portion.
