Chocolate. I absolutely adore chocolate, but only good chocolate. I've sought out and nibbled on hundreds of different bars and blends. Anything under 70% dark just doesn't do it for me. I've melted down chocolate bars and mixed in baking chocolate and reset it so it would be darker.

Whitman's? Russel Stover? Hershey? Reeses? Miss me with that please.

If you get the chance to try a single origin Ecuadorian dark chocolate it's amazing, complex, fruity and floral. All of the pretentious stuff people describe about wine is genuinely there in chocolate.

Nothing, really. If I'm picky about something, I usually just won't eat it.

I don't like skins on sausage or pulp in beverages.

I'll chime in with water.

There's so many different flavors of water. Just trying tap water in random places is such a different experience. Although I only specifically remember the worst. What the fuck was that bitter thing in Budapest.
As for mineral waters, I definitely go for Budiš in a glass bottle, chilled.

Any kind of sandwich, burger, taco, hotdog, etc. that is too overstuffed to pick up and eat pisses me off. If its open face or whatever and you're eating it with a fork that's fine but if its not then I need to actually be able to eat it without food going everywhere when I pick it up. Giant burgers you can't pick up or fit in your mouth are especially stupid and I hate them.

Burgers, sandwiches, kebaps, etc. Stay away with your stupid sauces. I want to taste the ingredients, not the sauce. No, not even your super fancy handmade burger sauce. The stupid thing about sauces is that you can't even take them off when you don't like them. They're sticky and smooth and get everywhere.

I see this from two different perspectives:

1. There are some ingredients I just don't like the taste of. But, in some recipes and if prepared properly, I'm fine with them. Green beans are an example. I don't like them. But creamy green bean casseroles are fine and vegetable soup with green beans is totally acceptable.

2. Then there are things like desserts that I'm picky about because if I'm going to screw up my metabolism and caloric intake for the day, it better damn well be worth it. I'm not going to waste my time on a substandard sugar and/or fat filled treat. I'm going to skip on that dry cake, jello salad, faux ice cream, fake chocolate sludge, etc.

Pizza. I came to realize when I first started traveling that being from Connecticut and having easy access to extremely good New Haven, Greek, and New York style pizza is a luxury. It's my favorite food. Whenever I travel, I make sure to try the area's so-called "best" pizza for at least one of my meals. It is seriously pathetic what some regions consider good pizza.

Sushi/nigiri.

I do not screw around with low quality or bad meats, especially fish meat. I had enough fresh fish when I lived in Japan to know what it's supposed to look and smell like, and if the nigiri I'm served smells any bit off I'm simply not eating it.

If your fish smells like fish, it's gone bad. Most types of fish if properly preserved should smell somewhat like clean seawater, with some variation by species

Edit: Also, if the rice looks dry or doesn't adhere properly, I assume the kitchen has no idea what they're doing and won't eat it

Icecream — I can't have a lot, so I only have it when I know it's highest quality.

Bagels. They MUST be toasted and topped with butter ONLY. It’s not that I don’t like cream cheese, it’s that I vastly prefer the taste of butter.

Of course, this all gets thrown out the window if we’re talking about some kind of bagel sandwich. Then whatever I like gets thrown on that thing, and toasting is optional.

I have unreasonable high standards for Mexican foods and their derivatives (TexMex, CaliMex, Burritos de Gringos, Jalisco, etc.)

Coleslaw. Mayonnaise has no business here, vinegar slaw or nothing.

American BBQ. There're a lot of regional flavors and differences but most of them are bad in my opinion. Memphis dry rubs and Kansas City molasses sauces are my 2 favorites

I'm very picky when it comes to pickles. I don't like the taste of standard dill pickles, only garlic dill pickles. I have only found two brands that make them the way I like them.

Anything that I cook well myself.
