It's convenient to have fresh flavors available to make cooking easier and not have to worry about making an extra trip to the market, just chop in food processor and place in ice cube trays, freeze and pop out to store in a plastic bag.  This is great for dishes I make at the last minute like Lemongrass Pork / Pork / BBQ Smoke / Recipes | Cooking with Aloha, Texas Style (cooking-with-aloha-texas-style.com) and KSP Lime Electrolyte Ginger Lemongrass Jello Shot / Tennis Snacks / Recipes | Cooking with Aloha, Texas Style (cooking-with-aloha-texas-style.com)
