Eat a whole jar to yourself today, kimchi fiends. It's "Kimchi Day" in Korea, so Google's published a Doodle dedicated to the ingredients that go into making the tangy fermented treat. You can spot the essentials in the Doodle: cabbage, red pepper flakes, ginger, garlic, fish sauce, green onion, carrot, radish, rice flour, and salt. They're ingredients you use to ferment kimchi in an onggi (clay pot). Of course, there are hundreds of regional recipes for kimchi, so this is just a general idea.
