1:1 ratio for maximum flavor on my salad, and recommend starting with this ratio and adding more oil if you find this too tang.
Try :
peanut butter- make a creamy and thicker version by adding peanut butter or another nut butter. Start with 1-2 tablespoons and add water as needed if it is too thick.
ginger- add fresh or powdered ginger for added flavor. Start with ½ teaspoon powdered and 1 teaspoon freshly grated.
lime- add a squeeze of fresh lime juice to give this a citrussy twist
sriracha- up the spice level with ½ to 1 teaspoon of sriracha
vegan- use maple syrup in place of honey
paleo- swap the soy sauce for coconut aminos
