Baked Queso de Bola and Spinach Spread

Assemble the crostini: preheat oven to 300°F. Brush bread slices lightly with olive oil and arrange on a baking sheet. Bake until crisp, dry, and slightly golden, about 5 to 8 minutes. Place in an airtight container and store at room temperature until ready to serve.

Make the spread: preheat oven to 350°F. Melt butter in a heavy-bottomed saucepan over low-medium heat. Sauté shallots and garlic until tender and fragrant. Add white wine (if using) and cook until it evaporates.

Add heavy cream and sour cream; simmer gently. Add spinach and queso de bola. Stir until cheese melts. Turn off heat and season with black pepper. 

Transfer spread to a baking dish. Bake for 15 minutes in the preheated oven or until hot and bubbling. You can also bake it in a turbo broiler set at 175°c. Serve hot with crostini on the side.
