This spicy, creamy stew gets its flavor from a base of onions, garlic, ginger, and green curry paste. You can use prepared green curry paste or your own homemade version. Because every curry paste is different, you may want to adjust the amount you use according to your taste. We used Thai Kitchen during recipe testing. Serve this stew on its own or with rice. For a variation on this recipe, use cabbage in place of the Brussels sprouts.
