To contribute to your results, I did the same thing around 3 months ago and thought I was insane to do this...TomLafinsky wrote: ↑ The sacrifice one does in the name of science...
And the results are:
50 pistachios with shells = 68g
50 Shells = 32 g
50 pistachios without shells = 38g
The scale I used is accurate to 1g which explains the small discrepancy in results. So now you have it! The shells represent 47% of the total weight.
I weighed all my shells and got an approximate 680g in shells alone.
While I didn't weigh the full bag itself...I will simply assume that I bought 1360g. So that's essentially half of the bag.
So yeah, shelled cost more per gram once the shells are removed. Unless people prefer "the flavour" of shelled and are willing to pay the extra cost.
