Bring a large saucepan of water to a boil. Add the edamame and 1 teaspoon kosher salt. Boil the edamame until bright green and tender, about 4 to 5 minutes, then drain.
Place the edamame in a bowl. Add the toasted sesame oil and salt, then grate the garlic clove into the bowl (using a microplane). Toss gently until everything is evenly coated, breaking up any clumps of the garlic that stick together. Add the chili garlic sauce, starting with less and gradually adding more to taste (we used about 1 tablespoon). Transfer to a serving bowl and serve warm, with a smaller bowl for the discarded pods.
