what do i do with food offerings? How long do i leave them out? Taking it away immediately feels wrong but i dont want mold
I have answered this before, but the answers are all in amongst a bunch of other questions, so I’m going to try to make this one more focused and detailed
It depends on the deity. There’s two categories when it comes to this — ouranic (heavenly, basically anyone not of the underworld) and chthonic (underworld). Additionally, food offerings to heroes would fall under the chthonic category in my opinion, since they’re dead.
When it comes to deities who have both ouranic and chthonic aspects (Hermes being the main one people think of for that, but also Persephone and Melinoë, and even Zeus) I’d say it depends on which epithet/aspect you’re offering to. If you’re offering to the deity’s chthonic side, do it the chthonic way. If not, do it ouranically. For Persephone, though, you could also do it depending on season/time of year as that dictates whether she is in the underworld or not at the time of your offering.
Now into why it actually matters.
You can eat offerings to ouranic deities. You can’t eat offerings to chthonic ones. The ‘why’ is not something I’m completely sure on, just that that’s the way it is. However my bestie did suggest this last time I mentioned not knowing why:
@under-their-light hi, I love you
With ouranic deities, I always eat it. I see it as sharing food with my deity. I pray before I do it, saying the following:
“With the first and last to Lady Hestia, and a portion to Father Zeus, <name + epithet of the deity I’m specially offering to>, this <name of food> is for you. Take your fill, and I’ll eat the rest.”
You don’t have to say it like that, but I think this nicely covers all the bases and it works for me. Let me break down the structure.
Hestia is historically first and last in (ouranic) food offerings from what I’ve heard, due to her being the first to be eaten by Cronos and the last to be set free. This would be especially important if the food you’re offering is homemade, id imagine. I’ve also heard that a portion of all food offerings goes to Zeus, which is why he is included also.
Then I say the name of the deity I’m specifically offering to, as they can hear us when we say their names, and if I’ve a specific reason for the food offering, there’s usually a specific epithet to go along with that, so that would be added here. If I’m just offering food for the sake of it, which is most of the time (if I want something in return I tend to gravitate towards non-food offerings) then I will still use an epithet purely to make it sound more refined, but I’ll use a poetic one instead of a cult one, so that I’m complimenting the deity, not calling on a specific domain.
Then I tell them what I’m offering.
The ‘take your fill and I’ll eat the rest’ also comes from my aforementioned bestie and it’s been really helpful in making me feel more confident about it as I’m informing the deity that I am sharing it with them, so it doesn’t feel like I’m just rudely eating the thing I just gave them.
All this to say, you don’t HAVE to eat the food from an ouranic deity, but I find it to be the easiest method as I don’t have to worry about how long to leave it on an altar, and I don’t have to worry about ‘wasting’ food, or feel bad when I do eventually dispose of it.
So, onto chthonic. We can’t eat food to chthonic deities. I also have a massive thing about throwing food away. I know if it’s offered to a deity it isn’t technically waste, but it still feels wasteful. So I offer food a LOT less to my heroes and chthonic deities, I must admit.
But I still do it. And that’s by offering food that I know won’t get eaten. Leftovers of a meal? Offer them to a chthonic deity or to a hero. Something will go out of date before I have the chance to eat it? They can have it. Someone didn’t finish eating something that they’d never tried before because they didn’t like it? Offer it to a deity. Ran out of time to eat a thing while on my break and I can’t take it with me? My gods can have it. There’s almost endless scenarios. It actually LESSENS any guilt about wasting food, because it’s not getting eaten anyway, so at least they can have it.
This is also the same for libations (liquid offerings) you can drink to ouranic but not to chthonic. Pour it on the floor for chthonic deities (you can do this for ouranic too, but again, I usually don’t waste it if I have the opportunity not to)
If you didn’t want to eat them for the ouranic deities, I’d say my only rule for how long to leave something on an altar is ‘don’t let it rot’. Leave it out as long as you want, as long as it remains hygienic. And when you do decide to throw it out, inform your deities that’s what you’re doing.
