I recently got a $20 bakers couche from brotform.com and tried it out for the first time today. I floured it up liberally and whomped up a couple of sourdough loaves with sesame seeds for tomorrow (Thanksgiving).
The loaves expanded lengthwise more than I expected as they rose in the couche so I had to sort of scrunch them a little as I maneuvered them onto my oiled baking sheet so they would fit, and they wound up with some minor "accordian pleats". A nice skin formed on the loaves as they rose in the couche and that made slashing easy as pie. Somewhere along the way the "accordion pleats" mostly went away and the loaves turned out rather pretty!
I'm not really sure how to get the excess flour off without losing sesame seeds but I'll try to deal with that tomorrow. Aside from the unexpected lengthwise expansion and the excess flour problem I think I like this new couche!
Any input from others on "couche techniques" would be most welcome!
