Guess so because if no chocolate would taste like tuna then...

• Answer:

  The scent and taste of food depends on chemicals called "esters". Our tongue recognizes only four general categories of these esters--sweet, salty, bitter, and sour--but our noses are far more sensitive to nuances and differences. Combined, the input of our noses and our taste buds are what determine various flavors. There literally millions of different combinations of esters, and those combinations are unique to each food. So even though tuna and salmon are both fish, they each have a unique combination of esters, creating a distinct flavor for each one. Furthermore, esters are altered with heat or refrigeration--which is why cooking and serving temperature makes such a difference in flavor.
