I just ran across these facts:
Bananas possess just one odor-producing chemical, which when you smell it you say, "That's a banana." Tomatoes, on the other hand, fashion more than 400 fragrant chemicals, and by some very complex means our Lord Jesus uses them to form the smell we call "tomatoes." Finally, the aroma of coffee has something in the order of 800 different compounds
that create its unique odor. And the number of new chemicals that scientists are discovering in coffee each year continues to grow!
