Having a meal in remembrance of a loved one? Wondering what might be appropriate?
It’s simple: you modernise the ancient Greek tradition and sacrifice something valuable and edible over a fire with lots of appropriate holy herbs and vegetables. The God/ess (your mum?) selects the stuff S/he wants by making it ascend heavenwards. You share in religious blessing by scoffing what’s left behind. Cook it correctly, don’t burn it: you don’t want to make the God/ess fat.
Having said this,
I am not a priest of Zeus,
I may have the details wrong.
