Notes
Whisk before heating: Make sure the sugar is fully dissolved, as this ensured the sauce thickens smoothly.
Always make a cornstarch slurry: never add the cornstarch directly into the hot liquid. I've made this mistake more than one time and The result is a clumpy texture that no-one likes. In hot liquid, the outer granules of cornstarch gelatinize instantly, leaving powder granules inside. Always mix cornstarch with cold liquid until it dissolves and only after that pour it slowly into the hot liquid.
Don't overcook it: the sauce thickens quickly once you pour cornstarch. It might look thin at first but then it will thicken very rapidly when cornstarch is activated by the heat.
Adjust for the dish you'll use the sauce for: if you will be using this sauce as a marinade, make it thinner by reducing the cornstarch amount. If you're glazing salmon, meat, or vegetables with it a thick consistency is better.
Taste as You Go: Don’t be shy to adjust the flavors as you mix. Want more honey? Go for it. Want less ginger? That’s fine, too.
Low Sodium Option: Use tamari instead of soy sauce to reduce the sodium content without losing flavor. This also makes this sauce gluten-free.
Sweetness Adjustment: Opt for simple sugar if you prefer a sweeter taste.
Microwave method: For those preferring a quicker method, combine all but cornstarch and water in a microwave safe bowl then microwave for about 1 minute. Add the cornstarch with water mixture and mix well, microwaving for 30 seconds more after that.
Make it Gluten-Free: Use tamari sauce or certified gluten-free soy sauce
