This whole thread is pretty triggering to me. People think that if the recipe is exact enough, it’ll come out perfect the first time and they won’t have to make any tweaks sure to their ingredients, their equipment, or the environment.
There’s a reason why I generally won’t make a recipe for the first time for guests.
Dude, you’re so wrong about all of this. Bakers typically use the same ingredients from the same providers. So they know what to expect.
And when it comes to a dough or batter, a baker can tell by look and feel if the proportions are off and will adjust accordingly.
