dude that one (the google one), there's WATER around the noodles, the sauce is too thick (inconsistently spread (I don't know about you but I don't enjoy CHEWING SAUCE CHUNKS)) and idk what type of noodles those are but they really look undercooked to me.
lkjdfjd i don't understand you. i think what you have to realize is that, as steel said, a lot of sauces tend to be cut with wine other shit for the sake of taste obviously and this leads to them... looking absolutely nothing like ragu and not having such a THICK, HEARTY APPEARANCE. pomodoro sauce, for example, will always have that buildup of "water" at the edges of the plate because some sauces just have a high liquid content. also dude, not all sauces are supposed to be
mashed up what are you eight. those are not chunks of sauce, they're vegetables. actually a lot of tomato-based sauces contain stewed tomatoes and even more sauces in general contain chunks of other random vegetables (zucchini, squash, peppers, and so on). it's not inconsistently spread, that's just the consistency of the sauce.
also i believe those are a particularly exotic type of noodle called.......... spaghetti and they don't look undercooked at all sorry! honestly i am kind of wondering whether you actually eat REAL FOOD or if you just think the shit that comes out of a can of marinara sauce is how all sauces are supposed to look.
