Order a jar of cured mullet roe anywhere around the Mediterranean and you will hear it called something different. In Egypt it is batarekh (بطارخ), the amber “caviar” sliced thin onto buttered bread. Cross to Italy and the very same delicacy becomes bottarga; sail west to Provence and it is boutargue; travel to Japan and it is karasumi. One ancient food, a dozen names — and every one of them points to the same thing: pressed, salt-cured fish roe that has been prized along these coastlines for thousands of years.
This week we are putting the spotlight on our own expression of that tradition, Bottarga Esmeralda, and showing you exactly how to bring it to your table.
One roe, many names: batarekh, bottarga, boutargue
The story of cured mullet roe is really the story of the Mediterranean itself. Food historians trace its origins to the Phoenician coast, from where it spread with Arab settlers into Sicily and Sardinia and eventually reached the south of France. By the Middle Ages it was valuable enough to be listed as cargo in Mediterranean shipping records, and the Renaissance writer Platina claimed he remembered eating nothing more exquisite.
What changed from port to port was mostly the name:
- Batarekh — Egypt and much of the Arab world, where it is often called “Egyptian caviar.”
- Bottarga (or botarga, sometimes spelled botargo) — Italy; the grey-mullet version is bottarga di muggine.
- Boutargue or poutargue — Provence, in the south of France.
- Avgotaraho — Greece.
- Karasumi — Japan, where it is counted among the country’s three great delicacies.
The classic fish behind all of them is the grey mullet, whose roe sacs are salted, pressed and dried until they firm into a dense, amber lobe. One name, one fish, one method — carried across an entire sea.
Meet Bottarga Esmeralda
Bottarga Esmeralda — our dried mullet roe, the Caviar of the Mediterranean — is Duke’s Gourmet’s take on this lineage. It is made from wild-caught grey mullet from the south-eastern Mediterranean Sea, and it keeps things honest and simple: just mullet roe and sea salt. No preservatives, no additives, no artificial flavors, and it is certified kosher. Each whole lobe runs roughly 3.17 to 4.2 oz — enough to carry you through weeks of finishing touches, because a little goes a remarkably long way.
How bottarga is made
Traditional bottarga and batarekh share the same patient process. The whole roe sacs are lifted intact from the fish, salted, hand-pressed to drive out air and moisture, and then dried until the color deepens to amber and the texture turns firm enough to shave. Slice into a lobe and you will often see it is built from many smaller sacs pressed together — the mark of the real, hand-worked article. Bottarga Esmeralda follows that same minimalist path: roe and salt, nothing else.
What it tastes like
If Parmesan is concentrated dairy, bottarga is concentrated sea. A single shaving delivers a wave of briny, nutty, deeply savory umami — oceanic without being fishy, rich without being heavy. That intensity is why cooks treat it as a finishing ingredient rather than a main event: a few grams transform a plate.
How to enjoy Bottarga Esmeralda
The beauty of a whole lobe is its versatility. You can go fully traditional or completely modern with the same jar.
- The Egyptian way: slice it paper-thin and lay it over warm buttered bread or toast as an appetizer or meze, finished with a squeeze of lemon and a thread of good olive oil.
- The Italian way: grate it generously over spaghetti aglio e olio for an instant spaghetti alla bottarga, or fold it through a finished risotto just before serving.
- Brunch: shave it over soft scrambled eggs or avocado toast for a salty, savory lift.
- Raw bar: grate it over freshly shucked oysters, or shave it onto bruschetta and crisp salads.
Because the flavor is so concentrated, start with less than you think you need. Keep the lobe tightly wrapped in the refrigerator, and bring it back toward room temperature before slicing so it shaves cleanly.
Choosing your bottarga — and beyond
A whole lobe like Bottarga Esmeralda gives you the most control: you decide whether to shave wide ribbons for a dinner party or grate a fine, even dusting over pasta. Look for a firm, dense lobe with a clean amber color — the hallmarks of properly cured mullet roe. If you want to explore the full range of cured roe, from whole lobes to ready-grated jars, browse our Mediterranean bottarga collection.
And if you love that briny, from-the-sea pop but would rather spoon than slice, our gourmet caviar pearls deliver a similar burst of flavor with no knife required — a natural companion to keep in the pantry alongside your bottarga.
Batarekh, bottarga, boutargue, karasumi: call it whatever you like. Once you have tasted it shaved over a plate of hot pasta, you will understand why the Mediterranean has been making it for three thousand years — and why a single jar of Bottarga Esmeralda tends to become a permanent fixture in the kitchen.
