Many instant ramen noodles are wavy because their shape helps compact the noodle block and creates spaces that let water penetrate. Fresh ramen may be straight or wavy depending on production.
How the shape is formed
Commercial noodle-making equipment can wave or crimp strands before steaming and drying or frying. The finished waves help form a compact block while separating strands enough to rehydrate.

What happens during cooking
The noodles soften and unwind somewhat in hot water. Curliness is not a direct measure of quality or of whether a noodle contains egg; many ramen noodles do not.
Choose by texture
Thin or thick, straight or wavy noodles each interact differently with broth. Check the package’s recommended cooking time rather than assuming a curlier noodle needs longer.

Frequently asked questions
Are all ramen noodles curly?
