Heat the olive oil and butter in a large sauté pan over medium-high heat.
Add the garlic and shallot and cook for about 1 minute.
Remove the pan from the heat and carefully add the brandy. (If the pan ignites, stand back and allow the flame to disappear, which it will in a few seconds.) Return the pan to the heat and bring to a simmer,
Simmer until the brandy is almost totally reduced, about 2 minutes. Add the broth, cream, mustard and Worcestershire sauce and stir to combine, then cook for a minute to thicken. |
