I'm not sure how to describe the flavour of guacamole. I've eaten it plenty of times before to know what it tastes like, but I'm not good at describing how food tastes. However, its primary ingredient is avacado, and it also has lime in it. I think that it tastes good, though I must admit that its appearance is a bit unappetizing. Don't be afraid; try it, and if you don't like it, don't eat it again, at least until the next time you feel brave.
