Birdlady says
I love this recipe I’ve made it twice now and it’s so good both times , I’m wondering why the mayonnaise though? Do you think it would be equally as good without it?
Surup says
Thank you so much! I'm so glad you liked this recipe. Actually the Mayonnaise is used to cut the astringent taste of Broccoli. However you can replace it with greek yogurt as well.
