You either love Marmite or you hate Marmite. I love it, I eat it several times a week, I get through jars of the stuff and it remains one of the few luxuries on my grocery shopping list. I love it so much that for the past few years it has been more of an addiction, I never go more than a few days without Marmite on toast as a snack. At any time of the day too. The only problem with a Marmite addiction is that if you forget to take some on vacation you really begin to miss it.
A few years ago I spent a couple of months in America, where my then girlfriend and now wife was working on a student exchange program. I forgot to pack my Marmite, it was the one thing that was irreplaceable. After several weeks of cravings I eventually found some for sale online which was shipped to me within a few days and tasted exactly the same as the British Marmite, it was an import. That place online was, strangely, Amazon.com.
