Crema Gelato - Crema flavor is the most popular flavors in Italian gelateries. It is as simple as gelato can get....milk, eggs, and sugar. It has a rich, yellow color from the deep hue of the egg yolks.
A proper Italian gelato di crema is sort of like vanilla ice cream, only in place of vanilla, you infuse the milk with a modest grating or shaving of lemon zest. This doesn't turn it into lemon ice cream, itself a cool dollop of heaven. What happens, rather, is that the small-volume scent of lemon makes the eggs eggier and the custard creamier.
