Hi! If I have a 7lb corned beef do I double the recipe? Thank you! Also, can I omit the horseradish and just use mustard?
I have not tried cooking a 7-pound corned beef in the slow cooker so I can't give you a definite answer on that but I do think that doubling the liquid might be too much. However, you can omit the horseradish!
