What smells like garlic aside from garlic?

Asafoetida (asafetida)

Ferula assafoetida

Fam: Umbelliferae

Asafoetida gets its name from the Persian aza, for mastic or resin, and the Latin foetidus, for stinking. It is a gum that is from the sap of the roots and stem of the ferula species, a giant fennel that exudes a vile odour. Early records mention that Alexander the Great carried this "stink finger" west in 4 BC. It was used as a spice in ancient Rome, and although not native to India, it has been used in Indian medicine and cookery for ages. It was believed that asafoetida enhanced singers voices. In the days of the Mughal aristocracy, the court singers if Agra and Delhi would eat a spoonful of asafoetida with butter and practice on the banks of the river Yamuna.

Spice Description

Asafoetida is a hard resinous gum, grayish-white when fresh, darkening with age to yellow, red and eventually brown. It is sold in blocks or pieces as a gum and more frequently as a fine yellow powder, sometimes crystalline or granulated.

Bouquet: a pungent smell of rotting onions or sulfur. The smell dissipates with cooking.

Flavour: on its own, extremely unpleasant, like concentrated rotten garlic. When cooked, it adds an onion-like flavour.
