Pound Cake with Mascarpone Sauce

This is a clever Italian-style finish that turns a plain pound cake into something worthy of a dinner party: a billowy, brandy-laced sauce of mascarpone, egg yolks, and whipped whites, spooned generously over thick slices and topped with fresh berries.

The technique is essentially a zabaglione crossed with mascarpone mousse. Beat yolks and sugar to a pale ribbon, then blend in the mascarpone gently, do not overmix or the sauce will break and weep. Folded egg whites are what give it lift, turning a dense cheese sauce into something that holds a soft peak on the spoon.

Room-temperature mascarpone is the detail that matters most. Cold cheese fights the eggs and leaves lumps, where soft mascarpone blends smooth in seconds. Take it out of the fridge 30 minutes before starting.

The brandy is understated at two tablespoons, just enough to round out the sweetness and echo the berries. Strawberries or blackberries both work, sliced so the juices weep into the sauce.

Kitchen Tips

• Use pasteurized eggs if serving to vulnerable guests, the sauce is not cooked.
• Fold the egg whites in two additions for better lift, do not stir.
• Refrigerate at least 30 minutes before serving so flavors meld and texture sets.
• Slice the cake slightly warm if possible, it accepts the sauce better than stone-cold cake.

Variations

• Swap brandy for amaretto or dark rum for a different aromatic profile.
• Serve over toasted angel food cake for a lighter base.
• Add a spoonful of lemon zest to the mascarpone for a brighter, citrusy finish.
