I Made Kenji’s Food Lab Classic Meatloaf

Yes, it took a very long time, I did all the prep on Saturday, baked it on Sunday. Tripled the quantities to make three loaves.

I followed the recipe exactly with the exception of substituting Kitchen Banquet for the marmite (three stores didn't have it – found that idea in the comments).

My curmudgeonly father-in-law:
"Well, now I finally know what meatloaf is supposed to taste like."

It's phenomenal. Well worth it if you have the time.
