The argument of it in a dish is not the one I am making.
If I sat the two pastas next to each other, with no accompaniments, the ingredients from the same brand/homemade situation are the same. Yes, they taste the same. The textures would undoubtably be different, sure. Prepared properly and equally, the taste is the exact same pasta to pasta.
If I grinded 10 different variations in a food processor, you can’t pick out which one used to be farfalle and which one was spaghetti. Do the same for Hershey’s chocolate vs Dove I’m sure you can tell a difference.
