Mabon marks the second harvest. The bounty of nature is dwindling. Earth begins to pull her fertility from the land. Humans and wild animals alike scramble to gather as much food as possible in preparation for the hard winter ahead.
Grains are appropriate for Mabon—particularly corn. Corn chowder, boiled ears of corn, and creamed corn fit Mabon symbolism well.
Beans, squash, and all other fall vegetables are also perfect for this festival.
