Tacui is a traditional type of pasta originating from Liguria. The pasta is usually made with a combination of chestnut flour, wheat flour, water, and salt. The ingredients are kneaded with lukewarm water into a smooth and firm dough that’s left to rest.
After a while, the dough is rolled out and cut into diamond (lozenge) shapes. The pasta is boiled in salted water, and it’s then typically served with a pesto of basil, walnuts, and marjoram. In the past, wheat flour was expensive, so the locals used chestnut flour because chestnuts are abundant in the mountains surrounding Liguria.
