125g per person if you only eat that, 80 to 100 if you eat something else too

Good brands you can usually find outside of italy with not outrageous prices are Rummo and Garofalo, less good but still okay, and at a generally lower price, you can usually find Voiello or De Cecco

Barilla is the most common, but outside of their spaghetti I'm not a big fan

There are a bunch of others, but these tend to be easier to find

That's all, thank you for coming to my TED talk

I keep seeing variations of this theme. My mom always does the opposite. Like 12 people are coming over for thanksgiving or Christmas and she makes one little bag of noodles.

I once made spaghetti without water

Can never make too much pasta. Better too much than too little. Can always throw the leftovers in the fridge and microwave it the day after or make a lunch box. Of course, if you are struggling with overeating, then idk. Make to little maybe.

I just put ⅓ of the 500g packaging

This is bizarre to me, I have literally never had this problem. Even if you don't have a scale, pasta is sold in standardized package weights and recipes have the weight you need so like if it says 12 oz then that's 3/4 of a 1 lb package. Then again, I always just scale the recipe to the full pound of pasta anyway because it's easier to deal with instead of just having 4 oz of pasta sitting around trying to figure out what to do with.
