Shallots are sweeter than onions and have less of a bite. Dried shallots are great to have around when you don't have fresh shallots and you don't want to bother with dicing onions. Adding dried shallots to moist dishes will be enough to rehydrate them, but you can also hydrate them yourself in a bit of warm water before adding to salads, bread doughs, or pastas.
