Blanching ingredients for secondary?

[PatsFan1985]

Hey everyone. I'm working on an imperial pale ale, and was planning to dry hop it with an ounce of Amarillo pellets, as well as add in some orange zest and some coriander. I don't have any vodka handy, so I was hoping to perhaps steam the orange zest and coriander briefly to sanitize them. Will this do the job without ruining the flavors? How long should they be steamed for?

Heating, via steam or whatever, them will remove at least some - if not most of the aroma. Preserving the aroma is pretty much the point of putting them in 2ndary instead of the boil. Go get some vodka.
