Why are two packages of red Sichuan peppercorns so different?
I used to have a package of red Sichuan peppercorns that I used for kung pao. The aroma was very nice, but the numbing effect wasn’t particularly strong.
After about 8 months, I ran out and bought a new package, this time from a different producer. Both packages are labeled as red Sichuan peppercorns, but they are very different.
The old package had quite a lot of black/dark pieces mixed in, which I had to pick out (my older daughter got that job 😄). The new package has almost none of those black pieces.
The aroma of the new peppercorns is also completely different. To me, it’s almost citrusy.
I used the same amount of the new peppercorns in a kung pao recipe with ingredients I’ve used many times before. The result was extremely numbing, almost unpleasant, and the aroma was so different that it honestly tasted like I had used a completely different spice. To my wife as well.
So I’m wondering what could explain such a big difference when both products are sold as red Sichuan peppercorns?
And, more importantly, is there a way to mitigate the strong numbing effect and get closer to the flavor/aroma of the older product?
Thanks!
