I have often been asked, why I use raspberries as a key visual for BBB. 
There is a simple reason for that: I think, raspberries perfectly fit BBB...

Raspberries are like great brands:
Everybody knows them and (nearly) everybody likes them.

Raspberries are like BBB:
All-purpose deployable and though down to earth.
A basic fruit, you can conjure a lot of (cooking wizardry).

Last but not least raspberries are also pink like the BBB brand logo and a very good sign for my (also private) passion for food.

...and this is why I just find it to be logically consistent to use raspberries as a brand visual for BBB.
