Yes, I know. I really should have got over that by now.
Secondly, ester sounds exactly like an angry snake just before it bites you.
Thirdly, my Chemistry teacher at school was so terrifying that the mere mention of any chemical substance is enough to make me feel as if someone has dripped liquid nitrogen down my spine.
Now, however, I've decided to make my peace with esters, and so I've been brave and had a peek at wikipedia.

Ah. That's good...
But, hang on, esters do seem to have their good side. They give us lots of lovely scents - jasmine, cherries, apples, bananas, pineapples, strawberries, butter, honey, cheese and wine.
