- Using a thin knife and work in a bowl, cut the kernels from the cobs; you should have 6 cups.
 - Working over another bowl, scrape the cobs with eh back of the knife to release the corn milk; discard the cobs.
 - In a large skillet, heat 3-tablespoons oil over moderately high heat.
 - Add the onion and sliced garlic, and cook, stirring occasionally, until soft, about 4 minutes.
 - Add 4 ½-cups corn kernels and the corn milk, and cook, stirring occasionally, until the corn is tender crisp, about 6 minutes; season with salt and pepper.
 - Transfer to a blender, and let cool slightly.
 - Wipe out the skillet.
 - Add 1 ½-cups water to the blender with the corn, and puree at high speed until very smooth, about 5 minutes.
 - Strain the puree through a fine sieve set over a large bowl, pressing on the solids.
 - Return the corn puree to the blender, and add the spinach, chopped jalapeños, and 1-tablespoon juice, and puree until the spinach is finely chopped and the soup is green.
 - Cover and refrigerate the soup until cold, at least 2 hours.
 - Meanwhile, in the same skillet, heat the remaining 1 ½-cups corn kernels, and cook over moderately high heat, stirring occasionally, until crisp and golden, about 1 minute.
 - Transfer the corn to a small bowl, and refrigerate until cold.
 - In a small saucepan over medium heat, combine the vinegar, 1-cup water, crushed garlic, and sugar; bring to a boil.
 - Place the sliced jalapeños in a mason jar, and pour the pickling mixture to cover; let sit 8 minutes, then seal with a clean lid.
