I have never had an Ina Garten recipe that I don't like. My mom cooked a lot of her recipes growing up. One of my favorite things about her is that she insists on using high quality ingredients. I've prepared her recipes the cheap way and her way, and she's right - better ingredients make better food.
This recipe is for a Mustard Horseradish Sauce intended for a beef sandwich. My family uses it as a steak sauce so we can get as much as we want on every single bite of beef. I have been eating it for years and I LOVE it! I always knew it had horseradish in it, but everything else was a mystery to me until today.
I still love it even though the main ingredient is mayonnaise, which I hate. Also, I chopped up a few leaves of Italian parsley to sprinkle on top, mostly for color because the flavor is not overpowering.
Mustard Horseradish Sauce:
3/4 cup good mayonnaise
1 1/2 tablespoons Dijon mustard
1 tablespoon whole-grain mustard
1/2 tablespoon prepared horseradish
2 tablespoons sour cream
Kosher salt
Whisk together the mayonnaise, mustards, horseradish, sour cream, and a pinch of salt in a small bowl. Serve at room temperature.
Yield: 1 cup
