Tim in Merv's Hot Bread Kitchen (Attleborough / Norfolk) has been trialing these for us for the past few weeks. I snapped these photos in his bakery yesterday afternoon. He uses our normal paper mini muffin cases in the moulds and fills the paper cases right to the top and then piles on the topping as you can see in the photos below.
The cherry muffins with the big sugar nibs are to die for :-) I'm not surprised they've instantly become very popular ! Now I've managed to get a load of sugar nibs myself - I'm dying to have a play at home.
