I prefer Heinz ketchup to any kind of kind of upmarket home-made or bottled tomato sauce.
In fact my heart sinks when people bring it out. It's always pallid with chunky, semi-cooked onions in it.
And green bits. Could be gherkins, coriander, mould - I don't know, I just know that I don't want it.
That would be with burgers and I'd combine with English mustard.
For bacon sandwiches it's brown sauce; HP - Daddies is very downmarket. Fruity is an abomination.
After years of red sauce, I like chips with mayonnaise now, so feel I am slowly becoming middle class. I have to have salt and vinegar with fish and chips.
Whenever I play Danny Baker's Sausage Sandwich game on R5L on Saturday mornings I plump for brown sauce and if that option is taken I go for no sauce at all.
I have Dijon mustard but that option is disqualified in the rules.
