Let us now consider the logistical problems involved with a blind chef.
Should she reach the competition rounds, her kitchen station will not be an issue: all they have to do is let her set it up so that she knows exactly where everything is (down to the last millimeter), let her label the temperature settings on the stove, put Braille buttons on all relevant appliance activators, give her some time to memorize it all, and she's good to go. The pantry -- now that could take a while, along with the tool shelf. But eventually, she'll have the whole thing written down in her head and all will be well, as long as you can get the other contestants to yell "Behind you!" at all necessary moments plus the field can get used to a sweeping cane at awkward moments.
But then we have the challenges in the field.
Did anyone bother telling you where the butter was? How about where the oven is? The distinctly non-labeled oven? How far does the cooking surface go on that grill, anyway? Any hot portions that aren't on the home model where someone's hands could land because another contestant forgot to yell "Behind you!" Cooking in a parking lot? Anybody fill the potholes? Oh, hanging pots, what a very bad idea...
Now let's talk presentation. Sure, no one else has ever seen that ingredient either, but at least they know what color it is. Did you know using it will turn your sauce to the rough hue of sewage unless you counterbalance? Let's hope so. Can you artistically arrange your plate when you can't see the results? With enough time, practice, and people giving you feedback, absolutely -- which isn't available here.
By the way, remember that Identify The Ingredients challenge?
She could qualify for the last eighteen. She might be one of the most talented cooks in the field. But the producers are going to need some fast thinking to accommodate her -- and if there's anything reality TV hates to do, it's think.
