@ai6yr@jhv I don't understand this complaint.
Sure, volume != mass. The circled lines in Joe's first post illustrate the absurdity.
But, when cooking & esp'ly baking, it's very convenient to have guidelines for converting an old-style by-volume recipe to one where you weigh ingredients.
So, yeah, explaining that volume != mass would be correct in the best sense of "technically correct" and as usual, would not be useful. So, seems like copilot did the right thing here.
