Being a good ole country boy I always try to celebrate the cycle of nature.
Today is LAMMAS (sometimes called 'Loaf Mass'); one of the countryside's more important festivals, where we celebrate the new wheat harvest. Traditionally it's on August 1st when we bake and eat our first loaves of bread made with flour from the recently harvested wheat crop. It's the celebration of a good harvest, of thanks for nature's bounty, and a wink at the necessary ingredients of sun and rain from the sky above.
Here in France, HUGE Lammas-style round loaves used to be baked that would last any decent sized family a whole week. In deference to more ancient beliefs, a cross was (and still is) drawn across the bottom of such loves with the bread knife, before the first slice was removed.
When I buy large round loaves I always continue this tradition, regardless of its significance; a little like not walking under ladders.
