This is a very… Strange thing, questioning the balance of pasta, but…
Spaghetti Bolognese and Lasagne have essentially the same inputs. Both types of pasta are, if manufactured raw by the player, made from 4x Flour. However, raw spaghetti has 2 less nutrition than raw lasagne. This only gets considerably more pronounced when you turn them into a finished good.
Again, they have the same inputs - exactly the same inputs. Hell, spaghetti requires Food Cooking 3, whilst lasagne only requires Food Cooking 2. The outputs are wildly divergant, however; spaghetti and lasagne both produce 8 portions. Spaghetti yields Nutrition 25, Quench 0 and Enjoyability 12 (I’m checking these numbers on a Gourmand character,) whilst the Lasagne yields Nutrition 38, Quench 5 and Enjoyability 45.
Why in the world would anyone ever make Spaghetti Bolognese when they could make Lasagne? If they have a pasta extruder, they can make whichever they prefer from flour, and even if not, raw lasagne’s not hard to find.
