how to beef up a beef sandwich with my mom’s sweet and sour mustard

This is my ultimate beef sandwich. Fabulous bread, some roasted beef leftovers, gherkins, onions, tomatoes, avos and then my mom’s sweet and sour mustard. This specific mustard is something I had to make weekly when I grew up. It’s the South African sweet & sour mustard (soet mostert) but without the condensed milk. It goes perfectly with beef + pork + turkey and just about anything else.

So the real secret that I am letting you in on is mom’s recipe … so you better give it a try and then keep the recipe to yourself. Bon appétit!

If you substitute the mustard with 1 teaspoon of mustard powder you can also use it as a “mayonnaise” for your potato salad.
Use the “mayonnaise” with cooked onions and you have “slaphakskeentjies”.
It keeps very well in the fridge for over a week.
