Since the pickling process takes some time, be sure to make all you need in one batch. If you need more brine to submerge all the asparagus, just multiply the recipe.
Add the jalapeno, ginger and asparagus to the hot brine. Make sure the asparagus is submerged in the liquid. I've done this in Tupperware, shallow casseroles, etc. Use something that's just wide enough to hold the asparagus so that the liquid can be as deep as possible.
