In a small skillet, combine the cardamom, coriander and cumin. Toast over medium-low heat, swirling and tossing frequently until fragrant, about 3 minutes. Allow to cool slightly, then peel and discard the husks from the cardamom pods. Transfer all of the toasted spices to a spice grinder along with white peppercorns and salt. Grind to a fine powder. Set aside.
In a separate bowl, zest the limes. Set aside.
Put all the prepared ingredients and Doenjang paste into a blender. Turn on the blender, adding just enough water so that the blade catches the ingredients. Puree until smooth, but only add as much water as needed to blend. Transfer to an airtight container and refrigerate for up to 2 weeks, or freeze for 3 months.
