In this recipe, I will show you how to keep the roe fresh for months without it becoming soggy, moldy, or developing unpleasant odors.

Total time: 15 minutes preparation + 2-3 days of waiting for the preservation process
Number of servings: Depends on how much roe you have, but generally, the recipe is adaptable for any quantity.

The history of fish roe is fascinating. These delicacies have been consumed for centuries in various cultures, appreciated not only for their taste but also for their nutritional benefits. Roe is rich in Omega-3 fatty acids, vitamins, and minerals, contributing to a healthy diet. Today, I will share my secret for keeping them fresh and delicious.

Step by step:

1. Preparing the roe: After removing the roe from the fish, carefully remove the membrane that binds them. This step is crucial to prevent mold formation. Use a wooden spoon to mix the roe, being careful not to crush them. This homogenization will help to even out the texture.

2. Adding salt: Add a generous amount of kitchen salt. Even if it seems like a lot of salt, do not hesitate to add it. The salt will not only preserve the roe but also change the texture, helping to prevent excessive liquid formation. Continue mixing with the wooden spoon until the liquid binding the roe becomes whitish.

3. Filling the jars: Prepare the clean, dry jars. Fill them with the roe, making sure they are well compacted. It is important that the jars are full enough to avoid air formation inside.

4. Covering the roe: If you have filled the jars but not completely, add a thin layer of sunflower oil on top of the roe. This will act as a protective layer, preventing contact with air and mold formation.

5. Storing in the fridge: Close the jars with the lids and place them in the refrigerator. After 2-3 days, you may notice a reddish liquid at the bottom of the jars. This is a sign that not enough salt was added. Do not worry, open the lids and drain the liquid. Add a little extra salt over the roe and mix again with the wooden spoon to even it out.

6. Observing the color: At first, the roe will be a light brown, but after a few days of preservation with salt, they will take on a vibrant orange color, indicating they are ready to use.

Practical tips:
- Make sure all utensils and jars are well sterilized to prevent contamination.
- Use high-quality salt, without additives, for the best results.
- You can add spices or herbs to the mix to customize the flavor, but be careful not to affect the preservation process.

Frequently asked questions:
- Why can roe spoil? If not salted enough, the roe can develop bacteria or mold.
- Can I use other types of salt? It is recommended to use kitchen salt for moisture and flavor control.
- How long can I keep the roe? Properly preserved, roe can last for months in the refrigerator.

Possible variations:
- Try adding a bit of lemon juice for a fresher taste.
- Experiment with different types of oil, such as olive oil, to change the flavor.

Serving:
Roe can be served on slices of toasted bread, with finely chopped onion or as part of an appetizer platter. They pair wonderfully with a cold drink, such as a dry white wine or craft beer.

Calories and nutritional benefits:
Roe is an excellent source of protein, essential fatty acids, and vitamins, with a variable caloric content depending on the type of fish, but generally, 100 grams of roe contains about 250-300 calories. Consuming roe can support cardiovascular health and cognitive function due to its high Omega-3 content.
