When hurricane season hits its peak and the storms are damn near constant, sure, I’ll pour out my offerings to Thor.
But we name those storms. We personify and anthropomorphize them. We hail them as beings with their own energy and presence. Even people who claim no belief in any higher power will do this.
“Remember Andrew? He was a bastard.”
“Irma’s angry; she’s going to hit us hard.”
The strongest? We never call another storm by that name, and in the areas heaviest hit, you see a sharp, sharp decline in children bearing that moniker. Around here we know–you don’t give a kid that name, it has too much power and rage behind it. It’s ill luck.
So I offer to the storms, too. To tell them, hey–I see your power, your might, your rage. I see your majesty. Please, slow down. Please, be calm. Transform your rage into gentle showers and winds that are just strong enough for us to know it’s you.
Be kind to us, great storms; show us your power in a way that causes the least amount of harm.
For things that can be burned, Oak trees are associated with Thor. (For strength). Dried oak leaves or oak twigs would be excellent, particularly if you draw the rune Thurisaz on them (Thurisaz is Thor’s rune, a representation of Mjolnir.) Onions and garlic are sacred in the Norse tradition, and are good offerings to any of the gods. Bits of dried onion or garlic would also be a good bet.
I usually just say “ ___, I offer this to you, and hope that you might enjoy it.” Then either set it on their alter and clear away after a couple days (I usually pour it out under a tree if I do this) or drink it myself.
Odin likes mead, red wine, whiskey, coffee (strong and black), beer, and black tea.
Thor likes…almost anything that his human buds are willing to share with him. Not a huge fan of overly sweet things though. He loves beer and mead, but Gatorade is surprisingly happily accepted too. (A WARRIOR SHOULD BE HYDRATED!!!) And again, whatever you’re drinking? He’d probably love some of that to share. It’s as much about the sharing with his humans as the offering itself to him.
Loki likes mead, and ANYTHING TOOTH ROTTINGLY SWEET. Soda? A+. Coffee composed more of cream, sugar, and flavor syrup than coffee? Yes good. Tea with enough milk and sugar and in it to stand a spoon up? Excellent.
No worries! Thor is one of the most absolutely enthusiastic gods about any sort of thanks. He love humans, and loves it when you interact with him.
Make a nice meal in his honor, and invite him to share it with you! Light a candle, and tell him, aloud, how grateful you are. Do something good in his honor! All of these would be excellent ways of offering him thanks.
