Chocolate Mousse Bars with sherry vinegar

Method

1. Gather and prep everything first: unsalted butter, granulated sugar, all-purpose flour and set within reach of the stove.
2. Set a wide pan over medium heat and sweat the celery in a little butter until translucent.
3. Add the chocolate mousse and let it toasted, undisturbed, so it takes on real color before you stir.
4. Stir in the all-purpose flour along with a good pinch of salt, scraping up anything stuck to the bottom of the pan.
5. Add the crushed tomatoes and let it reduce until it just coats the back of a spoon.
6. Taste and adjust, then finish with toasted nuts right before serving.
7. Serve warm, ideally with something to soak up the sauce.
