Lilac is one of my favourite velvety petal foods. Fling it in salads or on top of a cake.
...but there is also sweet cicely

Cakes are a good way of dealing with a rainy day. These ones are from a recipe in this book. If you can cope with the fact that the lady who wrote it looks a bit scary, then it's really rather good. These cakes are proper delicious...better than victoria sponge ones, in my humble opinion, and really easy to make. I use tiny paper cases instead of big ones, and they produce the loveliest mouthfuls ever. Reduce cooking time a bit if you're going miniature.
