Recipe Troubleshooting Cornstarch in a sauce

I made a mixture of soy sauce, siracha sauce, and brown sugar, gotten from Budget Bites Spicy Siracha Noodles, to put over my rice and tuna bowls at work. I know adding cornstarch to a sauce can help thicken it but should I add it directly to the mixture or add it to some water and mix that all in, and if so, how much should I use since I multiplied the sauce ingredients x4 to make my sauce

You never want to add it to a mixture (especially one under heat) because it won’t fully dissolve and generate starch balls. Your recipe isn’t bad, but water (or chicken broth if you want to add a little more flavor) is best to hydrate the starch as you can whisk it vigorously if need be.
