1 teaspoon butter
4 large shallots, peeled and sliced
1 pinch salt
250 ml red wine
500 ml veal stock
salt and freshly ground black pepper to taste
Step 1
Prepare all the ingredients.
Step 2
In a saucepan over medium-low heat, melt butter. Add shallots and a pinch of salt. Cook and stir the shallots until caramelized and browned, about 20 minutes, stirring occasionally.
Step 3
Add red wine and bring to a simmer. Reduce heat to low and cook until the wine is nearly evaporated and the pan juices are thick and slightly syrupy. Keep a close eye on the mixture to avoid burning. Add veal stock, return to a simmer, and cook until reduced by half and the sauce is slightly thickened, about 10 minutes.
Step 4
Strain the sauce through a fine mesh strainer set over a container. Tap the strainer with a spoon while straining and squeeze out the last remaining drops of sauce from the residue. Season the sauce to taste with salt and black pepper.
