Need help re final internal temperature for baguettes?
A bit of backgroundL I've baked whole wheat loaves for many years in bread pans. Near the end of the bake cycle I quickly insert a probe themomenter and take the loaves out of the oven when the internal temp is 201 degrees. The other day I made sourdough baguettes for the first time: 70% bread flour, 20% whole wheat and 10% rye. 68% hydration, 500 grams per loaf, about 14 inches long and 2 1/5 inch diameter when removed from oven. Oven was heated for one hour at 470 degrees, bake was for 12 minutes. My starter is maintained daily at room temp and was 100% hydration, and approx 20% of total build up. Steam 2 times first 8 minutes. So far, so good
Here is my conundrum: When I inserted my probe themomenter after 10 minutes, I expedted to read 190 degrees or so indicating another 3-5 minutes or so of baking to get it to an internal temp of 201 degrees. It read 218 degrees at minute 10! I fully inserted the probe into one end so a good portion was inserted and thus trying to avoid the heat of the oven registering the temp rather than the inside of the loaf. The probe is working as I later put it into boiling water and it registered 212 degrees. Perhaps the slightly thinner ends were that hot? Can they get that hot and still be moist inside? And yet they were just starting to brown nicely not quite there yet, thinking they needed a few more minutes to brown. A thump showed the ends sounded amost done and the slightly thicker middle needed a few minutes more. I removed the probe, let them bake another few minutes and out they came. I thought all breads were done at 201-205 or so degrees. My oven is accurate and I also have a themometer in the oven at all times.
The good news is they came out great, slashes spread nice, moist and airy crumb, great flavor and will keep well but I can't help think totally accidental. I will pursue yeastless sourdough without yeast, another new adventure in baking. Should I not bother with themometer and use the thump method to judge whether they are done? Internal temp targets? Any feedback on others experience would be appreciated! Thank you all...
