So far, my 30 inch slot seems quite limiting--when I select that option I'm down to 1 or maybe 2 choices vs a half dozen for the larger size, searching so far GE, Miele, Bosch.
Even the $8000 Miele, which does have 'steam injection program cooking', doesn't have truly continuous cooktop temp controls--it's a 1 to 9 power scale. That's much better than the 5 settings on the electric range I grew up with, but still not great. When you're pressure cooking something for 30-45 minutes at pressure, you want just that gentle puff puff puff, and that takes precise control.....that's where I'm most often fussing to get things *just right*.
And the people on the Bosch website chat can't do any more than read the manual, which only says that the auto-shut-off settings vary by power selected, and won't tell me if the setting required to keep a 16 quart stockpot simmering for meat stock will let me run it for 6 hours without having to reset over and over. All they can do is read the manual that doesn't say.
It was much easier shopping for the gas range.
