Not the biggest mayo fan, so I only used a half-cup and kept the rest of the ingredients at the same level. Loved the fresh ginger and so did the rest of my family. I feel like there could have been a wee bit more flavor, but I'm not sure what of. Definitely complimented the burgers, though.
I liked this sauce, but it was very mayo heavy - that might be ok for most people, but I happen to dislike the taste of mayo, so I would use less next time. Plus, you don't need that much sauce for 4 burgers, so you could easily cut it.
To be fair, though, it complimented the turkey burgers very well.
I think the description of the three stars fits this well--a good, solid recipe. It isn't amazing or the most delicious burger or sauce that I've made, but it's interesting and different in a good way. I enjoyed it and it made for a quick, easy meal.
