Soye (Dill Seeds) vs Saunf, Jeera, Ajwain & Shahi Jeera: How to Tell Them Apart
Five look-alike seeds and one mix-up with soybean. A side-by-side guide to dill seeds, fennel, cumin, ajwain and shahi jeera.
Dill seeds (soye) are flat, oval and light brown with a pale winged edge, and smell fresh and mildly sweet. Fennel (saunf) is bigger, plumper and greenish with a strong aniseed taste. Cumin (jeera) is thin, ridged and earthy. Ajwain is tiny and thyme-sharp. Shahi jeera is dark, thin and curved. Soye is not soybean.

The quick test at home
- Flatness: press a seed between your fingers. Dill seeds are distinctly flat, while jeera and saunf are rounder in cross-section.
- The edge: hold a seed against the light. Dill seeds have a thin, pale "wing" around the rim.
- Crush and smell: dill smells fresh and mildly sweet, fennel smells strongly of aniseed, and ajwain smells sharp.
Dill seeds in different Indian languages

Can you substitute one for another?
In cooking, caraway is the closest substitute for dill seed. Fennel works where you want sweetness, but it is much stronger. Dill seeds are not interchangeable with ajwain in traditional home remedies, so use the seed the recipe asks for.
