You can probably see that this recipe was one Mum saved from the label on a tin of sweetened condensed milk.  I thought slices and biscuits using sweetened condensed milk had gone out of fashion, but maybe not, as during this Covid crisis it’s been one of the items that’s been hard to get at my supermarket.  Maybe that’s because, like this recipe,  slices and biscuits using it are usually fairly quick and easy to make.  Great for baking and eating while stuck at home…………
