What's In a Name, that which tastes so sweet!

Walked into a supermarket and saw different little bottles with labels that said:

1. Jam
2. Marmalade
3. Conserve
4. Preserve
5. Pickle
6. Chutney
7. Coulis 
8. Marmite
   

Tried every single one of them.  Cannot tell the difference between 1,3 and 4 (Change the consistency and call it a different name?).  Hate 5 and 6. Rolled my eyes at 7.  Barfed at 8!

Tasting complete.
