Making cakes

..... for the birds.  My daughter gave me this, which was sent to her by her water company.  The idea is to stop people putting fat down their drains (?!*).

You fill the silicon container with left over fat, and add seeds which the water company actually provided.  Place it in the fridge for a while, and turn out when hardened.  Voilà!  One bird cake you can hang from a tree.

I didn't actually see any birds eating the cake, but it is all gone, so someone must have enjoyed it.
