The caramel filling inside was thick and gooey but I couldn't quite taste the salty part but it was still good if you just think of it as a caramel donut.
It works out 10p a doughnut which is pretty good.
I know it sounds weird but if you microwave it for 10 seconds, it warms up the doughnut so it was not so hard and the caramel filling is warm and delicious.
