Directions

1. Hull strawberries with a paring knife, cutting out the green tops only, and set aside until needed. Trim the crusts off bread; trim each slice into a square.
2. Add mascarpone cheese, vanilla, a few grains of salt, and confectioner’s sugar to a mixing bowl; whisk or use an electric hand mixer on high speed to beat until light and fluffy.
3. Pour in cold whipped cream, and continue to beat just until very stiff peaks have formed. Be careful not to exceed stiff peak stage, as cream will separate and become grainy. Spread each slice of bread with a thick layer of cream, going all the way to edges.
4. On 2 slices, place 3 whole strawberries tightly together from 1 corner of the slice to the other. Place 2 smaller strawberries, or a larger one cut in half, in the other two corners with pointed ends facing out.
5. Fill gaps with whipped cream, and generously cover strawberries with more whipped cream. Top with the other slice of bread, and press down lightly. Use remaining whipped cream to fill in the sides. Use the edge of a knife to square and smooth the surface.
6. Use a knife to make a mark on the top slice to indicate the direction of the center row of strawberries. Wrap tightly in plastic and refrigerate for at least 1 hour and up to 2 hours.
7. Cut sandos carefully on the diagonal with a serrated knife. For a nicer presentation, use a pairing knife to scrape any excess whipped cream from the cut surface of strawberries, to fill in any gaps, and to reveal their glistening red color underneath. Plate and serve.
