I think your challah look great, even the darkest of them.
I haven't made challah in a while, not sure I could do a 7-strand braid right now without some practice, even a 3-strand can come out lopsided if you don't pay attention. One of these days I'm going to make another attempt at a 6-strand, I'd still like to figure out how the one in 'Deli Man' was done!
I wont' be doing much baking the next week, it's time for the annual Barstow Alexander Institute, which is back to being in-person after last year's online version. And it's supposed to be in the 90's most of the next week, too, rather hot for baking. I might have to try some baking in my new grill when it comes next week, though. (For sure I will be trying pizza in it!)
