Aine is known as the Faery Queen.
Beltane is a great time to honor Her. Like the previous poster said, Apples are an excellent offering.
Burying an apple on Samhain, is sure to get her attention.
You can get her help in matters of love and fertility, healing amongst other things.
What a lot of people probably don't realize is that Aine, is also Anu, Mother of Gods and Tribe, Goddess of fertility, abundance and earth.
She is also one of the three aspects of the Morrigan. :)
