I mixed the egg whites and incorporated them in the mascarpone cream, stirring lightly.
I soaked the biscuits in milk and placed them in a rectangular bowl, then a layer of cream, biscuits, a layer of cream, biscuits, a layer of cream.
I spread the cream well and sprinkled lime peel on top.
Let it cool for a few hours, then it can be served.
