How to recognise spaghetti.
Spaghetti is a long, slim, solid strand with a circular cross-section. It is round rather than flat and usually about 2 mm thick.
Most dried spaghetti is extruded from durum-wheat semolina and water; fresh egg versions exist but are not the everyday Italian standard.
Spaghetti is strongly associated with southern Italy and Naples, though long dried pasta now belongs to kitchens across the country.
A smooth surface and firm centre when cooked al dente.
Use a tall pot or wide pan. Stir as the submerged ends soften, and finish in sauce for the final minute.
Why the geometry matters.
The slender round strands move easily through smooth tomato sauces and glossy oil, cheese or egg emulsions. Very large chunks cannot settle against them as effectively.
- Olive-oil emulsions
- Smooth tomato sauces
- Carbonara and cacio e pepe
