I haven't seen this recipe for years, but I was glad to be reminded of it when I saw Tamara Jane make them on GoodMorning a few days ago.
I couldn't resist making a batch. I used strawberry jam in the center of mine. Strawberry jam reminds me of my Nana. She used to make heaps of strawberry jam. So much nicer than the stuff you buy in the shops. I feel a jam making post coming up!
You can find the recipe here.
