From the sidebar write-up in the book, there is some additional historical information about this yummy muffin. "When Canadian Living Test Kitchen manager Daphna Rabinovitch was pastry chef at Toronto's David Wood Food Shop, these crusty-topped, apple-filled muffins were one of her best sellers." I have no doubt about that!
These muffins can be enjoyed any time and can be frozen and eaten later. Try one warm with butter - they're great!
