Few ingredients carry the flavor of the sea as completely as uni — the roe of the sea urchin, known in Italy as ricci di mare and prized on tasting menus from Tokyo to the Tyrrhenian coast. The catch has always been access: fresh uni is fragile, shell-bound, and gone within a day or two of harvest. Poseidon Sea Urchin Roe Pulp solves that problem elegantly: restaurant-grade Sardinian sea urchin, lightly salted and spooned into a jar, ready whenever you are.
In this spotlight we look at what sea urchin roe pulp actually is, why Sardinia is the place to source it, and the simple ways to put a jar to work at home.
What Is Sea Urchin Roe Pulp?
Sea urchin roe pulp is exactly what the name promises — the soft, edible roe scooped from inside the urchin and gently preserved. On a sushi menu you would see it as uni: those golden-orange lobes draped over rice. In a Sardinian kitchen it becomes the backbone of a silky pasta sauce. The jarred pulp is the same ingredient, simply freed from the shell so you skip the one genuinely difficult part of cooking with sea urchin.
The flavor sits right at the intersection of sweet and briny. Think of the clean minerality of oysters, the richness of custard, and a long, savory umami finish that coats the palate. A little goes a long way, which is part of what makes a jar so practical.
Why Sardinian Sea Urchin?
Sardinia's cold, clear waters have fed a sea-urchin tradition for generations, and the island's cuisine treats ricci di mare as a delicacy worth building a dish around. Poseidon sources its roe from this region — the same Sardinian coastline behind the brand's whole-lobe bottarga and cuttlefish ink. It is a part of the Mediterranean where seafood is handled with the kind of care that shows up on the plate.
That provenance matters because sea urchin is unforgiving: quality is set at the source and in the handling, not in the kitchen. Starting with carefully harvested Sardinian roe means the sweetness and delicate texture are already there when you open the jar.
What's Actually in the Jar
Poseidon keeps the ingredient list refreshingly short. The pulp is made of sea urchin roe and salt — nothing else:
- 100% sea urchin roe — pure pulp, no fillers or thickeners
- Just two ingredients — sea urchin roes and salt
- No preservatives or additives, and GMO-free
- Product of Sardinia, Italy
- Restaurant-grade — the same format professional kitchens reach for
- 1.76 oz (50 g) jar
At 1.76 ounces, a single jar is enough to finish several plates of pasta or build a tray of canapés — uni is an accent, not a bulk ingredient, so you dose it by the spoonful.
How to Use Sea Urchin Roe Pulp
The beauty of the pulp is how little it asks of you. Here are three reliable ways to enjoy it.
1. Uni Pasta
This is the classic. Toss the pulp through hot linguine or spaghetti with butter, a squeeze of lemon, and a spoonful of the starchy pasta water to emulsify. The residual heat warms the roe without cooking it hard, so it melts into a glossy, oceanic sauce in under five minutes. If you want a full walkthrough, our 20-minute uni pasta recipe lays out the ratios.
2. On Toast, Blinis and Canapés
Spread the pulp over warm buttered toast, or spoon small amounts onto blinis for an instant appetizer. A few flakes of sea salt and a drop of good olive oil are all the dressing it needs. For entertaining, uni canapés sit beautifully next to caviar and bottarga on the same board.
3. A Finishing Touch
Fold a spoonful into a risotto off the heat, swirl it into scrambled eggs at the last second, or stir it into a warm beurre blanc to pour over seared scallops or white fish. Used as a finisher rather than a cooking base, the roe keeps its silky texture and fresh-from-the-sea sweetness.
How to Store It
Before opening, keep the jar sealed and refrigerated per the label. Once opened, treat it like the fresh ingredient it is: keep it cold and use it within two to three days. Because uni's charm is its delicacy, it rewards being used promptly rather than stored for weeks — another reason the small 50 g jar is the right size for home cooking.
Pairing and Serving Ideas
Sea urchin's sweet-briny profile loves contrast. A crisp, mineral white wine or a dry sparkling cuts through the richness, and sake is a natural match — see our guide to what to pour alongside uni, caviar and bottarga. For a gourmet seafood spread, set the pulp beside grated Sardinian bottarga and a few caviar pearls so guests can taste the Mediterranean's three great cured-and-cured-adjacent delicacies side by side.
Frequently Asked Questions
What does sea urchin roe taste like?
Sweet, briny and rich, with a custard-like texture and a long umami finish. It tastes distinctly of clean seawater without being fishy — closer to oyster and butter than to anchovy.
Is the pulp raw?
It is sea urchin roe preserved with salt, not cooked into a conserve. Because of that, it shines when added off the heat or used as a finishing ingredient, so its delicate flavor and texture stay intact.
How much sea urchin is in one jar?
Each jar holds 1.76 oz (50 g) of pure roe. Since uni is used as an accent, that is enough for several servings of pasta or a platter of canapés.
Can I cook with it?
Yes — it makes an exceptional pasta sauce with butter and lemon, and it can be folded into risotto, eggs or butter sauces. For the best texture, add it near the end of cooking rather than simmering it.
The Bottom Line
If you have ever wanted to cook with uni but balked at cracking live urchins, Poseidon Sea Urchin Roe Pulp is the shortcut that doesn't cut corners: pure Sardinian sea urchin, two honest ingredients, and a format that turns a restaurant delicacy into a weeknight pasta or an effortless canapé. Keep a jar in the fridge and the Mediterranean is always ten minutes away.
