While doing some research in preparation for our upcoming beehive (cob) oven rebuild we came across some interesting materials. Among these, from the Canadian Museum of Civilization, is the Book The Bread Ovens of Quebec (BOILY, Lise, and Jean-François Blanchette. 1979).
Now out of print, but available in PDF form, The Bread Ovens of Quebec takes a look at the traditional outdoor ovens in Quebec breaking down the construction of a cob oven and includes items such as songs, and–removal of spells cast upon the oven/bread. Oh, my!
