Preserve capers in salt

This is one of the methods most used by Europeans, where the salt is used as a “natural” preservative of capers so that they can improve the shelf life.

To keep capers in salt, you just have to follow these steps:

  • Step 1. Choose capers

Try to choose the capers that look larger, as they are usually the ones that taste better. 

  • Step 2. Wash the capers

Wash with plenty of cold water to remove as much dirt as possible.

  • Step 3. Cut the stems

It is necessary for the recipe that you cut the stems of capers with a sharp knife.

  • Step 4. Drain the capers

As we will mix the capers with salt, you must let them drain for a while on a strainer to remove the excess water. Using absorbent paper as a complement may be a good idea.

  • Step 5. Mix capers with salt

Then, use the same strainer and place it above a large bowl to add enough without messing. Regarding salt, we recommend adding coarse or sea salt.

Ensure that the mixture is uniform so that the salt covers all the capers. As the hours go by, you will notice that the capers release water, which is advisable to remove and add more salt. You should maintain this dynamic for two days.

  • Step 6. Place the capers with salt in the sun

Then, leave the capers with salt in the sun on an aluminum tray. This way, they will dehydrate in a better way, so they will no longer release much water.

After two days, you notice that the capers have withered and wrinkled.

  • Step 7. Sterilizes a glass container

You will make the preserves in glass containers that you must sterilize, and to do that, introduce the jar and its lids to boil for 10 minutes. Then, remove them and dry them as best as possible so that they do not retain moisture.

  • Step 8. Pack capers with salt

By this time, we will have the capers as dry as possible, and therefore, it is the perfect time to keep them.

To perform the canning process, you need to put a layer of salt on the bottom of the glass container. Then you need to put a layer of capers, alternating the process until you fill the container. When you finish, make sure the container is tightly closed.

  • Step 9. Store in your pantry

You can store the container with your capers in salt in your pantry. It should be a cool place without sunlight coming in. Leave it there for a month. Then, you can taste them in your preparations.

This conservation process will allow you to have capers for more than 12 months.
