Hi Clanad,
Marmite has no comparison, although some may say similar to Vegimite if you've ever tried it.
Marmite is the scrapings/by product from the hop/yeast/beer barrels and is fermented and boiled and and and... then jarred (sp?)
I guess you have to invest and make some hot buttered toast and spread a tiny bit on it....
You'll either love it or hate it.
I thought it funny the price of $5.65! you wanna see how much I paid for Old Bay Seasoning!!!! and.... Aunt Jemimas Molasses.
Happy Trying Anyway :D
