350g flour Type 550
50g semola
5g salt
2.5g sodium bicarbonate, dissolved in water

Dissolve baking soda in a little water. Put the flours and salt into the pasta machine. The amount of water determines the machine. Knead and put in the die for spaghetti.

I let the pasta dry for about 20 minutes and then boil it for 3-4 minutes.
