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.
