I rarely ever have sauce with anything - no mayonnaise, ketchup, mustard or even salt etc
And without fail each time I have dinner with my friend she comments saying -
"eurgh don't you want sauce with that?!" ... or ...
"How can you eat that so dry?!"
But to me the food isn't dry or plain, I think it would only be to people who have to have sauce with their food because their taste buds are useless without it?
