It was tasty.

Alas, my brain has started to drop important parts on the floor, so I think probably I will not be able to describe my process. It did, however, involve knowing that I'd left something out of the dressing because it still tasted too much like mayo, and then having to dig way to the back of the lowest fridge shelf in search of the lemon juice.

I started with the Serious Eats guide, but went off in a few different directions. There being basically no way to make this sandwich kosher (not that I keep kosher, but I've learned that even using non-dairy components can have Bad Optics and therefore an uninformed onlooker might come up with the idea that it's A-OK to mix meat and cheese under the rule set -- and I do like to note modifications to my own recipes that would make those kosher) I did not use butter to toast the bread and warm + dry the sauerkraut. Because there was bacon grease Right There. Which I will have to deal with later, but there's a little less of it now.

Even though I wound up over-toasting the top side of mine, it was very tasty.

Belovedest took out the science experiment that I located between me and the lemon juice. Great thanks unto them. They devoured the first small sandwich on sourdough (they don't tend to like rye, or sauerkraut, but they got a small amount of sauerkraut anyway) so they got sandwich #2, on rye and with the normal amount of sauerkraut. Which I also may have overcooked.

I got the craving for them because Due To Reasons I got a Goldbelly gift card (reasons: helping beta something Very Important, and Slytherins don't like to leave an extraordinary favor uncompensated for too long) and therefore I was perusing the offerings there. And that struck me as the kind of thing that I can and should learn to make for myself.
