We do the same with jam ~ don't think it odd.
We long ago realised that there was nothing we could buy for friends and rellies that they could not and did not already buy for themselves so the obvious idea was to spread the word that from now on only consumable pressies would be given and we hoped they would reciprocate as our house was/is bulging at the seams with unwanted tat, jumpers that fit no-one, socks that will never be worn etc etc. Now we all exchange food and drink and compete to see who can make or grow their own or find unusual/regional foods etc. Works well I can tell you.
Eldest Daughter, who has a house and family of her own, was thrilled two weeks ago when I sent her flowers from the Scillies and a birthday cake from Yorkshire.. She actually cried because no-one ever thinks about Mum's wanting a cake as well but everyone expects Mum to make a cake for them. She was very, very pleased at the idea.
It works ~ sure the younger ones still get toys/electrical goodies but for the grown ups nothing but consumable items.
