How to Butterfly Shrimp

Butterflying shrimp before grilling or frying it helps it cook more evenly and gives the meal a pretty presentation. Shrimp are commonly butterflied by opening the flesh along the back. It is also possible to also butterfly shrimp along the inside belly, a process that's more time intensive but yields a unique result. See Step 1 to learn both ways to butterfly shrimp.

Steps

Preparing the Shrimp

Wash the shrimp. Rinse all of your shrimp to remove any sand or other debris before you start the butterflying process. Store the shrimp you haven't yet butterflied in a bowl of ice to keep them fresh.

Peel the shrimp. While you can cook shrimp that hasn't yet been peeled, butterflied shrimp is usually peeled before cooking. Peeling the shrimp opens up the flesh, making it easier to slice into it and create a butterflied shape. The tail may either be left in place or removed, depending on how you want your shrimp to look. To peel your shrimp,
- Pull off the head (if your shrimp came with heads attached).
- Pull off the legs.
- Peel off the shell - slip your fingers under near the head, then peel it off the body.
- Leave the tail on or remove it.

Remove the digestive tract. This is the black, grey or brown vein running along the shrimp's back. Before you can butterfly the shrimp, it needs to be removed. Position a paring knife at the head part of the shrimp, and gently slice along the shrimp's back to expose the digestive tract. Lift it out of the shrimp and wipe it off on a paper towel.
- If the tract breaks up into pieces, run the shrimp under a stream of water for a few seconds to wash it out.
- You can also use a shrimp deveiner to remove the digestive tract from smaller shrimp.

Remove the nerve cord. Turn the shrimp over to check if it has a visible nerve cord, which runs along the inside curve. If you see a dark line there, you might want to remove it. The nerve cord is edible, but it can affect the appearance of the dish. To remove it, gently run the paring knife along the nerve cord to cut through the flesh and expose it. Lift the nerve cord from the shrimp and discard it.
- You can skip this step if you're battering and frying the shrimp, or if you mind the nerve cord being visible.
- Removing the nerve cord is a little trickier than removing the digestive tract. Be careful not to slice the shrimp all the way through.

Inside Butterfly

Slice along the inside curve. Take the knife and make a deeper cut along the inner curve of the shrimp so that the body is divided into two attached halves. Take care not to slice all the way through the shrimp.

Rinse the shrimp and keep it cold. Place it under running water, then put it in a bowl of ice to keep it fresh while you finish butterflying the shrimp.

Back Butterfly

Use a knife to slice along the back curve.^[1] If you already removed the digestive tract, you simply need to make the cut you've already made deeper. Place the tip of your knife in the cut near the head of the shrimp, then cut along the back all the way to the tail. Don't cut all the way through the shrimp - just deep enough so that the body divides into two connected halves, like a butterfly.

Rinse the shrimp and keep it cold. Give it a quick rinse under cool tap water, then place it on ice to keep it cold while you butterfly the rest of the shrimp.
