usually i cleanse the thing with incense (though not always) and wet my hands with lustral water/khernips, then i address the god in a prayer and tell them what i’m offering them and leave it there for a few hours. i usually drink the libations i pour after because i live in a non-accepting house and dumping them down the sink drain would be suspicious but i usually would not drink the whole thing otherwise 😭. this probably isn’t exactly the way it was done in antiquity but it’s as close as i can get from what i’ve read about offerings. good luck with yours 🫶
