For many, going out for sushi can be a weekly or even daily ritual. It’s also one of the most widely used “interests” listed on online dating profiles — and for good reason. There’s something about sitting at the sushi bar, watching the sushi chef meticulously slice a piece of toro, then gently press it into a carefully formed mound of rice in the palm of his hand. It’s almost therapeutic. And just as there’s an art to making sushi, there’s an art to eating it.

Everything involved in the making of sushi — from the years it takes to perfect a rice recipe, to the sourcing of the seafood, to how that fish is sliced and presented — comes from years of training and tradition. If you’re going to chose omakase, and often relinquish the equivalent of a week’s paycheck for it, you might as well do it the right way.

So we consulted some sushi chefs, because chances are we’re all just doing it wrong. Here are seven cardinal sins of eating sushi.

1. Eating nigiri with chopsticks: When eating nigiri, the slices of seafood over pressed rice, use your hands, not your chopsticks. For those of us who feel a sense of pride after finally grasping a piece of sushi with a pair of chopsticks, this may come as a surprise — and perhaps a disappointment. But in Japan, it is traditional to eat nigiri with your fingers. When eating sashimi, use chopsticks.

2. Mixing wasabi in your soy sauce: Do not take a clump of wasabi and mix it into your small dish. Before your nigiri arrives, the sushi chef will have put a smidgen of wasabi on the underside of the fish — the amount determined by the type and condition of that seafood — before pressing it into the sushi rice. That is the intended amount of wasabi for that bite. Any more than that would be the equivalent of salting your food in front of the chef.

3. Eating miso soup before your sushi: Most Japanese restaurants in the United States serve miso soup as an appetizer before your meal, a prelude to your sushi combination set. In Japan, it’s the opposite. Just think of how the French serve salad after the main course, not before. A small bowl of warm miso soup is meant to be eaten last, after your sushi, as a way to help settle the food. So ask for it after the sushi, before the check.

4. Rubbing your chopsticks together: There’s something about a pair of wooden chopsticks that makes people want to rub them together. Maybe it’s an attempt at avoiding splinters; maybe it’s just a habit. Whatever the reason, just don’t do it. Or at least don’t do it in front of the sushi chef.

5. Using too much soy sauce: When dipping nigiri into soy sauce, don’t dunk the fish. Just use enough soy sauce to complement the fish, not overpower it. And be sure to dip your nigiri fish-side down. It will feel like you’re doing things backward, but too bad: The rice should not touch the soy sauce. (This makes sense when you think of all the times you’ve had to ask for a new soy sauce dish because yours is full of errant rice.)

6. Using your phone during dinner: The temptation to Instagram, tweet, Snapchat and Facebook every course of beautifully prepared omakase is always going to be there. But respect the chef in front of you and put the phone down. In fact, leave it in your purse or pocket, and only let that glowing screen resurface after you’ve finished your meal. Some sushi restaurants will have “no cellphone” signs posted behind the bar. Others will simply ask you to leave.

7. Ordering anything but sushi at the sushi bar: If you take a seat at the sushi bar, your intentions should be clear. Do not sit at the sushi bar, then tell the chef you’d like an order of chicken karaage, beef teriyaki with tempura, some garlic edamame and maybe a side of ramen. You can do that at a regular table. Respect your sushi chef. If you’re at the bar, it should be for sushi and only sushi.
