Kitchen Help

How do I ensure the roast is tender?

Slow cooking on low heat for several hours allows the beef to break down slowly, resulting in tender meat. Searing the roast first seals in juices.

Can I use different vegetables with the roast?

Yes, carrots, celery, and onions add depth, but you can include parsnips or potatoes for added flavor and texture.

How do I achieve creamy mashed potatoes?

Using Yukon Gold potatoes, butter, and milk while mashing creates a smooth and creamy texture. Adjust milk for desired consistency.

What can I substitute for beef broth?

Vegetable or chicken broth can be used, but beef broth provides a richer flavor. Red wine is a great addition for depth.

How can I thicken the gravy?

Remove some cooking liquid, whisk in cornstarch, and stir back in. Cook on high to thicken evenly without lumps.
