The hardest part for me is setting out offerings. cream and honey seem to be popular but I'm vegan and would really prefer not to use animal products.
Do you have any "local" sweet things? Where I'm from there are a lot of places that make maple syrup, for example, so I find it to be a good substitute since it comes from the land here. Making offerings of local products can be a nice way to sort of give back to the local land, and honor where you live. Dates, berries, other sweet fruits all work. Almond milk is a good substitute for cream. I'm not vegan but I love almond milk, use that for offerings a lot since I might not always have regular milk in the house.
And it doesn't have to be honey and cream types of things, wine, juice, olive oil, tea, fruits, veggies, baked goods, grains, nuts, incense, those are all options, and there's many more. As was mentioned before, time offerings are also important, too. Just spending time outside meditating, praying to the spirits, thanking them, spending time cleaning the land, or caring for it in other ways, growing your own herbs and plants which can be then used, in part, for offerings.
