Don't want to celebrate St. Patrick's Day?
How about the traditional Deitsch holiday of St. Gertrude's Day, known also by the name we use in Urglaawe of Grumbieredaag (Potato Day), which is the day we will honor the Frouwa.
Since the Deitsch population overwhelmingly identifies as Protestant or Anabaptist, the survival of this Catholic observance within the wider culture is interesting in its own right, even if it had been diminishing over time. Even most Christians (including those in the article below) acknowledge the heathen roots of the observance. While there are other connections that come up (particularly to Holle and to Freid/Frigg), Grimm (305) makes a connection between Gertrude and Frowa/Frouwa, and this is generally accepted by the Urglaawe community.
Potatoes have become a staple crop for the Deitsch since arrival, and tradition is that March 17 is the day to put potatoes in the ground. There are rituals to feed the Heinzelmenner or other Kowwold (kobolds) and to bring fertility to the garden. Specific foods include Datsch (a type of almost granola-like potato bread) and spring onions.
One thing I find important in this observance is the completion of the potato cycle. Potato bread from last year's harvest is consumed and offered to the land at the time that this year's crop is being planted.
The traditional Datsch recipe is posted in the Urglaawe Culinary Guild, and the program for the observance is below:
