In fact, if you want to eat ramen at home it’s the most practical (at least for the soup.) Actual ramen broth takes a lot of time to make from scratch.
I've heard that before, that many people like to buy Top Ramen (I think, IIRC it's considered better than Maruchan, but I may have it backwards) and then toss the noodles and keep the powdered soup pack. Much easier than the real thing, and respectably good given where it comes from.
Personally, I much prefer any of the Korean Nongshim brand for instant. (Shin Ramyun, etc.) The noodles have a better texture.
And for slightly more goodness, Asian marts will generally carry ready made broths and alkaline noodles. And one can whip up a broth from box stock if one wants something better.
Not sure what noodles to source, tho.
