The plunge has been taken!
I've ordered a new mixer.
I've reached the limit of what I can reasonably expect from my Kitchen Aid Accolade 400. It has served me well, and I've certainly learned a lot using it to mix and knead breads. But I want to mix larger batches of dough. I want to try formulas that demand longer kneading times, higher kneading speeds or both. And I don't need to prove that the Kitchen Aid isn't up to a job by destroying it.
Over lunch (Salami sandwich on my own sour rye, of course), I had a good talk with Deanne at Pleasant Hill Grain. Several on this site have been very pleased with their Electrolux DLX mixers from that vendor. When I visited their web site, I found they also sell the Bosch"Universal Plus" mixer. The Bosch and the DLX are more similar than different in capabilities, with each having a slight edge in one feature or another.
Without going through a blow-by-blow description of my decision making, I'll just say I have ordered the Bosch Universal Plus mixer. Honestly, the biggest draw of the DLX was that I know there are bakers here who know that machine and whom I could count on for tips and to answer questions as I get to know it.
Well, I guess we will have an opportunity to compare notes. That's something.
I expect to get the Bosch mixer next week. I couldn't possibly be lucky enough to get it before the weekend!
