1 - Mix the powders and the thinly grated lemon zest, add the water and mix for 5/6 minutes in the mixer with the leaf whisk.
If, instead, you knead by hand: arrange the powders in a bowl, start pouring the lukewarm water in the center, kneading initially with a fork. Once all the water has been put in, knead with your hands for about 7/8 minutes, folding the dough several times on itself.
2 - Cover the dough with plastic wrap and let it rest at room temperature for at least 30 minutes.
3 - Roll out the dough by hand, then with a rolling pin and then place it on the "guitar" to form your spaghetti.
4 - Now let's move on to the preparation of the clams. Take a bowl, put an inverted fruit saucer inside, arrange the clams on top with water and salt.
5 - Let the clams purge for at least an hour. Any sand released will remain under the saucer.
6 - Check that all the clams are still closed and put them in a pan with a clove of garlic and oil. Cover and cook over high heat, open the clams and cook for no more than 10.
7 - Sauté the pasta in the pan with the clams and your dish is ready!
