I present to you my versions of the Gyu Kaku sauces: sweet soy and hot and spicy. I cannot imagine eating gyu kaku without them. I am thickening them with a little bit of cornstarch because I think they have a slightly syrupy texture. Try not to go over the specified amount of ginger and garlic. It can be tempting but it will quickly overpower the sauces.
Combine all the ingredients in a small saucepan. Heat it over medium heat until it boils. Turn off the heat and let it sit for 10 minutes. Pour the sauce through a fine-meshed strainer to remove the pear pulp. The sauce is now ready to use and you can keep it in the fridge for up to one week.
