I get it. Unleavened bread has no yeast in it. And yeast is a symbol of sin, right? Not good for symbolising whatever it's supposed to symbolise, obviously.
So my beloved missus, who I believe is possibly the best cook in the world (although I do have a soft spot for chef Nigella Lawson with those magnificent knockers and all) is an absolute ace at baking sourdough bread.
And yes, sourdough bread - especially when toasted - is absolutely yummy. And it doesn't contain yeast!
So. How about it? Would it be OK if the Memorial emblems were sourdough bread instead of that ghastly unleavened stuff?
Enquiring minds need to know!
