Lemon Bar Bars with charred scallion

Method

1. Start by prepping your unsalted butter, granulated sugar, all-purpose flour so the cooking goes quickly.
2. Set a wide pan over medium heat and sweat the celery in a little butter until translucent.
3. Turn the heat up, add the lemon bar, and cook until deeply browned and aromatic.
4. Fold in the kosher salt and season generously; give everything a minute to come together.
5. Pour in the white wine, bring to a gentle simmer, and cook until thickened and glossy.
6. Off the heat, brighten it up with toasted nuts and a final crack of pepper.
7. Serve warm, ideally with something to soak up the sauce.
