Slice carrots and celery, place them in the freezer in ice molds.
Pour Pomì Tomato Juice in a glass and season with squeezed lime, a pinch of salt and a few drops of Worchester sauce. Pour in ice molds and let them also freeze.
Once all has freezed, take the molds out and quickly blend them in a mixer until it is slush-thick. Pour the smoothie in a big nice cup and serve immediately.
