There are many similarities and differences when it comes to broccoli and cauliflower, including their taste. These two foods definitely have a different taste to them and most people agree on this.
The way these foods look like also differ considerably with people comparing broccoli to miniature trees and cauliflower to puffy cumulus clouds. Even the way these vegetables smell differ greatly and you will be able to tell upon closely examining each.
Although both of these vegetables absorb flavor fairly well, cauliflower is generally better for dishes to compliment the already present flavors of the foods that are included in the dish which this vegetable is being thrown in with.
