I believe my CSO is now repaired and fully functional. I am most grateful. However I wanted to see if I could somehow achieve a one kg boule. Something that exceeds the capabilities of the CSO. I have an ancient Cuisinart Chicken Steamer (CCS). Could the CCS bake my one kg boule?
Dough from the Ankarsrum turned out fine.* The dough proofed perfectly in an hour and a half. Fitting the scored boule in the CCS was a little tricky but it worked. I used 60 g of water in the bottom of the steamer and placed the CCS on my well heated 470F 12x12x1 inch baking aluminum.** That may have been a bit much water as there is evidence of condensation, namely a few drip marks on the crust.
But baking progressed and the final loaf looked pretty good. Thing is it was stuck completely to the pan. The bottom crust still is. Tonight's bread will get the job done, but not my best experiment. Were I to assay CCS bread again I'd line the steamer insert with a Teflon disc and use less water in the steamer bottom. Still, sadly, I believe a one kg boule exceeds what can realistically be expected of the CCS. And for an 800-500 g boule the CSO is the way to go.
That said, if anyone else has a CCS I suspect it would work OK for baking smaller loaves. I never did like steamed chickens.
*as does almost anything with rum.
**were it made of steel I'd call it a baking steel.
