Sounds weird if you’ve never tried it before, but give it a go! Get the large-chunk versions and you get nice crunchy pieces of veg in your curry that really helps break up the otherwise “mushy” texture. And the vinegar flavour and salt really bring out more flavour in the dish!
I usually stir in about a tablespoon just before I eat it and get it properly mixed in. This amount doesn’t really effect the calories or macros very much.
Give it a go!
