Only if the weight is the same when dropped at the same volume. Outgassing can reduce the weight if powder is left open or the age is different.
I had 2 cans of IMR 4895. The same vintage. 1 went bad, the other didnt. I dont mix the same lot number. More so if i dont know at what temperature it was stored at.
My wife reminded me of this when I mentioned a few topics being talked about lately. Made me laugh... then made me think.
The Rule of "Probably Safe"
There once was famous baker who decided to share his talent with the world by offering baking lessons to promising amateurs. Several times a year, he would place ads in local papers and interview students by their submissions at a public tasting featuring equally famous food critics as judges. A very nervous fellow showed up with an exquisite smelling bread offering, featuring Marmite (a savoury food spread based on yeast extract) and poppy seeds, which all present loved. When he was chosen to be a future student, the baker asked, "What was the secret ingredient in your bread? I detected a flavor I'm not familiar with and, given I have an expert's palate, I need to know." The fellow him'd and haw'd then blurted out, "I'm not really sure, mind you but, it could be... ummm, the cat." "The CAT?" exclaimed the baker. "You didn't COOK...?!" "Oh, no-no!," said the fellow, "no, you see when I was punching down the dough after it's second rise, I added the poppy seeds and Marmite... then I got a call and had to leave for a few minutes. When I got back, the cat was on the counter, sniffing the dough. I'm not sure - in fact I'm pretty sure - she didn't walk across the dough or touch it... but after the bread went into the oven I did notice she had just used the box... But, I'm sure if there was any cat poo in there, it's probably very little and purrfectly safe!"
Would YOU (talking to the group, not
@243winxb ) like to try that bread? When you add things together, think about the Rule of "Probably Safe"
