This diet dial gives calories for common foods -- such as canned tongue (157 for three delicious slices!) It measures 5.125 inches across and is undated. It's in fair shape, although the window doesn't quite line up as well as it probably once did. I like the colors. I thought that, perhaps, they have faded, but a peek under the upper wheel shows that not to be the case.
I can't say I have ever actually used Knox Gelatine, have you? It was alleged to have nail-strengthening properties, but that's been debunked, I believe. It might be fun to try making a real fruit gelatine dessert without resorting to Jello. I notice that the little picture of the package says "sparkling" on it. What on earth? The little calf on the front is a nice touch, don't you think?
The Knox website is awful. Honestly: how can that be in 2017?
I have a cookbook that shows, in step-by-step photos, how to make your own gelatine from scratch using calves' feet! Thank goodness for Knox.
