@marlies Ketchup seems to be very difficult to make well for some reason, it seems. The one from Lidl is garbage too, even though all their other sauces are fine.
@marlies I really am curious why it is so difficult; from what I understand it is basically tomato + vinegar + sugar + salt, all of which are 'just' taste amplifiers of different kinds.
I have no idea either how there can be so much difference in flavour despite those basic ingredients.
