What is your favourite sauce of the big three :
Ketchup - Arguably the most widespread and common sauce used for flavouring your burgers, BBQ and other dishes. Can be considered the normie basic-guy option from others opinions.
Mustard - The yin to Ketchups yang, also widespread in dishes previously mentioned in Ketchup section, either exclusively used or paired with Ketchup combining the flavouring.
Brown Sauce - HP, Daddies etc this sauce is pretty popular in the UK (Where I live) and goes great on chips/fries and prior dish mentioning.
It is also a cardinal rule to be put into bacon sandwiches among the brown sauce community.
What is your favourite sauce to use?
It is quite different.
As least here in NZ, ketchup has a vinegary component to the taste, tomato sauce is more sweet.
