You don't want to know about Marmite. Is hell in a jar. Yuck. Either you love it or you really really really hate it. Surprisingly they sell it this way too. Yuck.
Oh, and an idea for a new flavour? Add the wonderful taste of jam (or anything else really), and get rid of all the taste of Marmite. Tada. Marmite extra extra lite. With Jam.
Cheers
Ps. Oh, and Marmite is well known (probably in an urban legend kind of way) as being the dog lover's favourite treat, just ahead of peanut butter. Easier to clean probably.....
I am 99% probably lying in bed right now... so don't blame me for crappy typing
