What To Do With Leftover Sashimi?

what to do with leftover sashimi

Recently, it’s been brought to my attention that there seems to be a lot of leftover sashimi.

The problem with this is that most people aren’t aware of what they can do with their leftovers.

So, today, I’ll be addressing the issue and providing some suggestions on how you can utilize your sashimi in different ways later on.

Firstly, let me explain why there are still bits of sashimi left over after eating it.

Why do you often have leftover sashimi?

First off, if you’re using the correct kind of knife it shouldn’t happen very often at all.

But sometimes mistakes are made when cutting up freshly-caught fish for example.

Or even cuts from kitchen knives while preparing said fish for cooking.

There are some instances where you’ve been trying to cut the flesh of a large fish but have been unable to do so.

In these cases, you can use your hands or even an ice pick to remove the flesh from the bones.

If you find that there are still bits of sashimi left over after eating it, then perhaps it’s because you’re not using enough soy sauce for example, etc.

Sometimes it may just be too much for one serving and that’s perfectly understandable.

So, what can you do with your leftover sashimi?

Searing it in a hot pan

The first thing I’d suggest is searing it in a hot pan with oil and salt.

This will give the sashimi pieces a nice caramelized outer layer which will provide some crunch as well as add another dimension of flavor to the bite.

This may be ideal for leftover flatfish sashimi, for example.

Mix it with rice

Another option is to mix it in with the rice.

It’s very common in Japan to eat leftover sashimi in this way, since it’s quick and easy and also provides a nice contrast of texture – crispy on the outside but soft on the inside.

Rice isn’t your only option though, you could try spreading some out on a plate or tray and using it as an ingredient in yet another dish – for example, adding it to some stir-fried vegetables together with soy sauce.

You can get creative here too by drizzling some wasabi over everything before serving, which will add more flavor to your creation.

Try removing the soy sauce

If you’re not too sure about how to incorporate your leftover sashimi into another dish, then perhaps it’s best to simply try and remove the soy sauce taste that will inevitably be present.

The first way I’d suggest is by boiling down your leftover sashimi with dashi stock and sweetened soy sauce (mirin).

This should ultimately take away or at least reduce any unwanted aftertaste.

Another option is to fry up some kimchi – since kimchi has quite a strong taste itself, using this as a base ingredient could help mask the soy sauce taste that’s left over from eating your boxed sushi or simple rice ball.

Alternatively, if you have any pickled ginger sitting around in the refrigerator then you can use this as a dip for your leftover sashimi.

Use it in other dishes

Your sashimi leftovers could be used as an ingredient in other dishes later on.

And you’re better off adding some of the sashimi bits into a hot pot or simmering them in a dashi broth – they should work well as an additional flavor enhancer/garnish for your stewed vegetables or meat dish.

If there’s any sauce leftover after enjoying your boxed lunch, then perhaps it would be best to use it up here by using some of these sashimi pieces again instead of letting it go to waste.
