I cannot remember exactly where I first came across this, but first taste and I was hooked. I am currently writing this review with a 454g tub laid at the side of me, and I can ensure that, although it was only bought for me a few days ago for my birthday, it will not last longer than a week.
I believe that the stuff was first created in America, which is not hard to believe, as all the best food for sugar lovers is over there (Darn country). To put it simply, the stuff inside is exactly what is says on the jar. If marshmallows could be put in a blender and made into a semi-paste, this is what it would be like. A spoonful of heaven. The tub itself, or at least the one I have is plastic, I do know you can get them in glass however, and the lid in a pull off, red one. The label is simple, but clearly displays what you, Marshmallow fluff, of course. Displayed in the top left hand corner is a yellow star displaying that the fluff has "No fat or cholesterol", can this tub get any better? and, true to it's word it is. The fluff doesn't have any fat, and the calorie content is surprisingly low (40 calories for 2 teaspoons).
On the back is a recipe of what you could do with the marshmallow fluff, but I am the first to admit that I just eat is straight out of the jar.
This, is just one of them foods, that is horribly addictive. Left alone with this tub can be seriously dangerous, for me anyway. It is absolutely full of sugar and positively gorgeous. I am not a massive lover of marshmallows alone, but I would give my left arm for a tub of this stuff. If nothing else, it is one of those things you have to try once in your life. I believe you can now get strawberry and raspberry tubs of it, which I can't wait to try. Although lovely, I would think of this as being a treat. It does suggest you can spread it on your toast etc, but I wouldn't think that it would add to part of a balanced diet.
Overall, I cannot recommend this stuff enough. It's gorgeous. If you have a sweet tooth, there is no doubt about it, you must try this. A big thumbs up from a sucker for all things sweet. Period.
