I too find the OP’s dilemma mystifying. It appears that the OP’s ideal toast complexion falls within the toaster’s knob range (with slight variation depending on type of bread). The obvious solution is to find the ideal setting for that perfect level of brownness and leave it there. Then just use self-control and wait for the inevitable (and often frightening) POP-UP! Easy peasy.
I, on the other hand, have a true toaster dilemma. You see, I like my toast black (no doubt some form of pica). Black as the ace of spades. But not black to the point of borderline carbon dust. I have a minuscule window within which to find my perfect level of toasty doneness.
Fine and dandy you say. Just find the ideal toaster knob setting that results in black, but not too black and leave the knob on that setting for eternity, or at least till the cows come home.
Well, guess what? You guessed it! My toaster knob doesn’t go high enough to toast my bread black. Not a little black. Not a lot black. No black at all! At the highest knob setting, my toast only reaches a complexion of dark brown. That is unacceptable. It would be exactly like ordering a medium-rare Kobe steak at a fine restaurant and being served a lima bean.
My only solution (short of hari kari) is to push my pre-black toast back down into the gaping maw of the toaster and give it a second cycle. But, whoa Nelly!, if I give it a complete second cycle, my toast will turn to potentially carcinogenic carbon dust. That’s almost as bad as dark brown for crying out loud!
So, I have to fiddle around with the knob and simply guesstimate where to set it for the all-important second cycle. Well guess what? You guessed it: the numbers and markers on my toaster knob rubbed off long ago (I blame it on the cat). I’m flying blind without a parachute carrying an iron anvil.
That, friends and foes, is a true toaster dilemma.
Every once in a while, after going through a loaf or two, I get toast that’s the perfect shade of black. Huzzah! But, by then it’s lunchtime and I don’t eat toast for lunch.
