If you want to use paper cases, use a good quality baking parchment squares with butter.
In order for the roses not too be soggy, dry up the apple slices on kitchen paper before assembling. You can also gently adjust or pull rose petals/apple slices with tongs if needed after baking if they need to look just perfect.
This really is very easy and the results are well worth the effort. Lovely with some thick cream. I used blackberry jelly instead of Apricot Jam and it was a very good combination. It is important to make very thin slices. My microwave was dead so I gently steamed the slices instead; this is not a great idea. Some of the slices get too soft, however hard you try. So, the microwave is pretty much an essential to get this right. - 22 Oct 2015
