What is the Bottarga?

Bottarga is a traditional food product typical of the Mediterranean coasts.

Made of grey mullet or tuna roe, salted, cured and aged in the ovarian sac for a few months.

It is an ancient method of preparation over 3000 years old. A method used by the Phoenicians and other civilizations that developed on the Mediterranean coasts.

The best quality bottarga it’s the one made with grey mullet roe produced in Italy especially in Sardinia and Tuscany.

While the tuna bottarga, less valuable than that of the grey mullet it is made on the Sicilian and Sardinian islands.

For centuries it has been a poor ingredient derived from fish waste. Nowadays it has become one of the finest ingredients of the Italian gastronomic tradition. Many starred chefs use it in their expensive menus, adding an extra aroma and flavor to their dishes.

Bottarga is quite expensive cured seafood, the price of the bottarga can vary from 70 to 300 euros per kilo. This because of the specific process used to get it, and also because there are very few producers in Italy. On the market, we can find it whole or already grated in a glass jar.

How producers make bottarga.

The Bottarga production process comprises four main phases. Extraction, salting, pressing, and aging the roe pouch. It has a cylindrical shape and has a variable weight, depending on the species of fish.

For example, the roe pouch of an Atlantic bluefin tuna or a yellowfin tuna can weigh even over 1 kg. While the roe pouch of a grey mullet the weight varies from 200 to 500 grams.

The first phase of production of the bottarga, is the most delicate and it is the extraction of the roe pouch.

Expert hands extract the pouch from the fish belly with extreme care so as not to damage the bag that contains the roe.

Immediately, they wash it in ice water to avoid the development of pathogenic bacteria during the next stages.

After washing, the following phases begin. The processing between grey mullet bottarga and tuna bottarga is a bit different.

Let’s see how.

The processing of grey mullet bottarga.

They sprinkle the grey mullet roe pouch with coarse sea salt, massaging the entire surface. The product is maintained on a horizontal wooden surface and is turned twice a day, adding more salt for several days.

Then the bottarga is ready for pressing. The period of this phase varies depending on the weight. It is necessary to ensure the drainage of the liquid inside the roe bag.

Watch this video to understand how traditional grey mullet bottarga is produced in Italy.

The processing of tuna bottarga.

The tuna bottarga, as we said, has a higher weight. The first phase after washing is pressing which varies from 2 to 4 days. Also, in this case, it serves to remove part of the liquid contained in the bag. After salting, the producers make a second pressing for 8 to 10 days, also this time with a constant change of salt.

The difference in processing between the two types of bottarga is the number of pressing.

For the tuna bottarga, there are two (before and after salting). While for grey mullet bottarga only one, which lasts about 2 weeks, from the first salting.

The last stage is drying. The producers hang the bottarga on the ceilings of the well-ventilated aging chambers and leave it to dry and age.

The aging time varies 30-40 days for the tuna bottarga and 45-90 days for the grey mullet bottarga. This time may vary depending on humidity and temperature conditions.

The types of Bottarga.

After understanding how manufacturers make bottarga that we find on the market, let’s review the most common types of bottarga.

The Bottarga di Muggine ( Grey mullet) also known as Sardinian gold is the most valuable and expensive. It has an amber color and a strong and at the same time very delicate taste. It is mainly produced in Sardinia and Tuscany.

Bottarga of Tuna: it is less precious, its color often varies from light pink to brownish. It has a much more intense flavor than grey mullet bottarga and a much harder consistency. The tuna bottarga is mainly produced in Sicily and Calabria.

In the islands of Sicily and Sardinia, we find another excellence: the swordfish bottarga. It has a lighter color and an intermediate intensity between the intense flavor of the tuna bottarga and the delicate flavor of the mullet.

So the next time you go to your fishmonger to buy a fish, look carefully when the fishmonger cleans it. Ask him if he can open the fish’s belly without letting the scissors or knife blades go too deep. if you are lucky to find a female fish, you may find the roe pouch inside.
