These are ordinary English Muffins but instead of using Wheat they are made from Tapioca and Rice Flour. Gluten free, wheat free and dairy free they are designed to fit into people's diets when they are cutting these out for health or medical reasons. I've tried other brands before and they are far too friable and just crumble at the slightest touch - especially when toasted.
My first complement for these was that they held together quite nicely, you couldn't tear them into halves like I ordinarily would (it makes the butter diffuse better and tastes nicer) but when sliced stayed together in the toaster well. Also when eating these I didn't notice a change in the quality of the bread like I have with other brands. While the bread flavour is different I can see these being a viable 'lighter' alternative for times when you don't want heavy bread snacks.
Also the packaging is really quite clever (two individually sealed air tight sections with two muffins in each) and means that the best before date was a good two weeks after purchase. For someone who only tends to eat this kind of thing on a weekend this is perfect. Much to my surprise I'd probably buy these again!
