Grapefruit Cupcakes with Avocado Frosting

Citrus and avocado are a classic salad combination. I never used to like avocado (I always it was a pointless use of calories) until I tried the grapefruit and avocado salad at a local restaurant. I can no longer remember the name of the restaurant, but I can remember the beauty of grapefruit segments, thin slices of avocado, pink sea salt and a hint of lemon zest.

When trying to create a completely original cupcake idea, I thought of this salad. I thought of just how it changed my opinion of avocado and what an amazing combination this would be, especially when topped with a little pink sea salt.

The cupcakes had a perfect texture. They were dense, but still quite moist and tasted strongly like a grapefruit creamsicle. The avocado was not overpowering and neither was the salt, but provided a complexity for the grapefruit to play against. It was sweet and salty and bitter all at the same time. At first it was a confusing assault on my taste buds, but after the initial bite, it became quite enjoyable.
