Gently softened garlic and shallots team up with meaty store-bought demi-glace to pack huge flavor into this easy make-ahead compound butter.
How to Make It
Step 1
Melt 1 tablespoon butter in a small saucepan over medium. Add shallot and garlic; cook, stirring often, until softened, 1 to 2 minutes. Remove from heat; let cool completely, about 10 minutes.
Step 2
Stir together shallot mixture, demi-glace, and remaining 7 tablespoons butter in a bowl until combined. Spoon mixture onto a piece of parchment paper. Roll up into a 2-inch-thick log; twist ends of parchment to seal. Refrigerate until firm, about 2 hours.
Make Ahead
Compound butter can be refrigerated up to 2 weeks.
