The simplest pasta is flour and water, and the ratio of flour to eggs is one egg per100g of flour, or go to the supermarket to buy ready-made food.

The ingredients of the sauce depend on what you do, just like asking what ingredients you need to cook Chinese food. How to answer?

It's summer now, and I'll give you a very famous recipe: pesto. No need to cook, it's a bit like our cold noodles.

The ingredients are: a lot of fresh basil (also called nine-story pagoda in southern China), pine nuts, (walnuts can also be added, or walnuts can be used instead of pine nuts according to personal preference), a little butter, a little olive oil, cheese powder (I personally don't think cheese is needed, the authentic one is goat cheese), garlic, salt, pepper and a little water. Put all these materials into the blender.

Have a good appetite!
