Grandma’s Mustard Sauce – Our “Ham Sauce” Recipe
During my time as head chef at a camp and conference center, I learned how much chefs value a well-made sauce: the right sauce can elevate a simple dish into something memorable. My grandmother was not a professional chef, but her recipes had that same knack for turning the ordinary into the extraordinary. I found this mustard sauce in her recipe box and it quickly became a must-have whenever we serve ham.

This warm, old‑fashioned mustard sauce offers a delightful sweet‑and‑tangy finish for baked or sliced ham. It’s simple to make, stores well in the refrigerator, and reheats quickly when you’re ready to serve.
Ingredients
- 2/3 cup white vinegar
- 1 cup white sugar
- 4 teaspoons dry mustard powder
- 2 eggs
Instructions
- Combine the vinegar, sugar, dry mustard powder, and eggs in a small saucepan. Whisk thoroughly until the mixture is as smooth as possible.
- Place the pan over medium‑high heat and stir constantly with the whisk. Continue stirring until the mixture comes to a gentle boil and begins to thicken.
- It’s normal for small cooked egg bits to form. If you prefer an ultra‑smooth sauce, press the sauce through a fine mesh strainer into a wide‑mouth jar or bowl.
- Serve the sauce warm with ham slices. Store any leftovers covered in the refrigerator and reheat gently in a microwave‑safe container or on the stovetop before serving.
