If the Rubinstar is anything, it is crispy. Crackling sounds chorused as I bit into it. This effect does not last long. The deeper I delved into the flesh of the Rubinstar the more pliable it became. The skin was the most crispy of the apple, overall the flesh was soft.
Confused was my experience with the taste. To my tastebuds the flavor was lemony. At first I believe I was mistaken, but as each bite tasted of lemon I realized that the Rubinstar does have pronounced notes of lemon. It is not alone with a lemony-flavor; it has tartness of a typical apple variety.
