Sadghetti
Spaghetti is nearly impossible to say without a childlike smile crossing your face, which is what makes the nature of this dish's oppressive depressive so impressive. There's very few sauces that don't work with this noodle, but this one found a way to do it. And with no toppings to distract you, you can really focus on how much it doesn't work.
Pictured here is Sadghetti, the most morose morsel.
