Sorry, no pic.
Argh! I even previewed and then viewed the thread to make sure it was there. Have modified the OP - hopefully it's there now.
I would definately say a tin - they have that basic 'heart-cake-from-a-tin' look.
Tin. Honestly, the small one could be as small as a 4". It looks pretty small.
I got out my Wilton heart pan set and stacked them up. Â It looks like it is the smallest pan on top of the largest. Â There are no measurements on the pans, but measuring crosswise at the widest part, the largest is a little over 14" and the smallest is 6". Â which is Â a ratio of 2.33:1. Â If you don't need that much cake, a 9" and a 4" Â would give a ratio of 2.25:1 which is very similar, if you wanted to size down. Â HTH Â
