Mayonnaise. It's the sperm of Satan, and should be banned. That so many people seem to think that the correct ratio of Mayo to chips is about 2:1. Argh! They seem to think it needs to be added to everything to render it edible. It's horrible, vile stuff, that should never have been allowed near food. That and the related crime that it's almost impossible to buy a prepackaged sandwich that doesn't include mayo.
Garlic. Overuse there of. Garlic is like bay leaves, you should be able to notice when it's been forgotten from the dish, but never be used to the point that it is actually noticeable as a flavour in it's own right. The people who seem to think there's some sort of matcho point in doing the "when it says one clove of garlic, i use a whole bulb!" are like the idiots who insist on ordering the hottest thing on the menu, or trying stupidly hot hot sauces. Cannot stand the smell of garlic.
Oh and wtf is with the trend of not cooking burgers properly? have people not got a basic understanding of food hygiene?
grumble grumble argh!
