Sea grapes, also known as green caviar and umibudo, are a species of edible green seaweed found in the ocean waters off the coasts of Asia and the United States. They are easily distinguished by their clusters of small, grape-like balls that range in hue from pale to dark green, with a texture similar to caviar.
While not widely known or eaten in North America, they are an important part of traditional Asian cuisine. But if you’ve never tasted sea grapes before and are wondering what they might taste like, here is more information about their unique flavor profile.
Sea grapes have a mild but distinctive flavor that is somewhere between salty and sweet, with a light crunchy texture. Many people compare them to caviar because of the similarity in texture and flavor, although sea grapes tend to be slightly sweeter than true caviar.
They can be eaten raw or cooked, but often take on additional flavors when cooked such as garlic or onion. The taste of sea grapes may also vary depending on where they were harvested since saltiness can increase near shorelines due to higher concentrations of minerals in nearshore waters.
Where Are They Found?
Sea grapes, also known as green caviar and Caulerpa lentillifera, can be found throughout the tropical and subtropical oceans of the world. They grow wild in shallow tidal pools between 2-3 feet deep and can be harvested both by hand or with small nets. Sea grapes are commonly found in warm coastal regions such as waters off of Indonesia, the Philippines, South India, and even parts of Florida.
These unique fruits appear in a variety of vibrant hues from bright greens to dark purples and blues. Egg-like in shape, the fruit hangs from stems that are connected to a rubbery base known as the thallus (stem).
They have a thin waxy cuticle on their surface that helps protect them from dehydration during exposure to air or prolonged periods underwater. Because of this protective layer, they tend to stay fresh for long periods after harvest.
Sea grapes should be eaten shortly after harvesting because their unique flavor will start to fade if they are stored for long periods of time. They can be enjoyed by themselves as a snack or added to sushi dishes or salads to bring a unique texture and sweetness that is unmatched in other fruits.
Many may assume sea grapes taste like seawater, however when freshly picked they offer up an intense flavor profile described by some as “salty” but with sweet undertones of grapefruit and citrus fruits.
How Are They Harvested?
They are harvested using a variety of techniques, ranging from hand-picking to mechanical collection. Hand-picked sea grapes must be carefully selected, as they contain fragile membranes that can easily tear. Mechanical harvesting methods employ a conveyor belt system which is equipped with claws that gently pick and collect the grapes.
The harvesting process also depends on the area of Origin. In Asia, most commercial production involves hand-picking mainly because the cost of mechanization is too high. In Australia and Africa, mechanical methods are used more often due to the large distances between production sites and the need for speed and efficiency during harvest time.
Many producers use nets or plastic sheets to cover their plants before harvesting; this is done in order to prevent any accidental animal (especially bats) interference with crop yields. It also allows producers to collect sea grape clusters as soon as they ripen instead of waiting for them all to mature at once.
The practice also ensures that only ripe clusters make it into the final product, which improves overall flavor quality in terms of sweetness and acidity levels.
Taste Profile
Sea grapes have an incredibly unique taste. They have a sweet and salty flavor and are unlike any other fruit or vegetable. The salty taste of sea grapes is often compared to that of caviar, with a salty brine flavor infused with a hint of sweetness. The texture of these delicate, small grapes is slightly crunchy, and they can be served both raw or cooked.
Let’s take a closer look at their flavor profile.
Sweetness
Sea grapes are a delightful, salty-sweet treat that has been popular in the Caribbean for centuries. Best harvested from wild plants near the shoreline, these tiny clusters of sweet, grape-like orbs lend an unusual flavor to many dishes. Their unique sweetness comes from their high natural sugar content and a delightfully mild saltiness reminiscent of the sea.
These unusual fruits are thin-skinned, crunchy on the outside and jelly-like on the inside. Countless small seeds can be found within their juicy flesh which becomes soft with cooking. When eaten raw they can have a tart flavor akin to dried cranberries or blueberries.
When cooked they develop into a pleasant sweet and sour flavor due to the development of complex sugars which can provide endless possibilities for chefs who are creative enough to explore this unique ingredient in all its forms!
When lightly salted, they offer a surprisingly delightful sweet and salty contrast, making them perfect for salads or as a garnish atop seafood dishes such as sushi. They can also be pickled for deep umami flavors and complexity or added directly into many types of dishes like soups and stews where their cool crunch is a welcome surprise!
No matter what cooking technique you use with sea grapes, you’ll be sure to enjoy the unique sweetness that only this unique ingredient has to offer!
Salinity
Sea grapes, also known as green caviar, are a unique type of sea vegetable. They are made up of small, bubble-like clusters that look like bunches of tiny grapes. The taste is often described as having a salty, briny flavor.
Their salinity is due to their high mineral content — mainly sodium and magnesium. This salty flavor adds a distinctive umami element to dishes and complements the sweetness of freshly caught seafood dishes and crispy vegetables. They can be eaten raw or cooked in the same way as other seaweeds and ocean plants. They are often used in salads, side dishes or as an ingredient for sushi rolls.
The bubbly texture contrasts with the smoothness and creaminess of raw fish or creamy cheese, making it an interesting addition to all kinds of dishes. In terms of nutrition, sea grapes contain vitamin C along with proteins and good fats like omega-3 fatty acids — they’re rich in vitamins A, B1, and B2 and minerals like calcium, iron, magnesium and sulfur.
Aside from their unique flavor profile and nutritious value, these little clusters have become popular around the world for their unique look — they make a striking garnish on various dishes!
Texture
They have a unique texture, which is comparable to caviar. Their teardrop-shaped orbs are crunchy, with a slightly nutty flavor that lingers on the tongue. The base of the grape is attached to a flexible stem that allows it to be easily consumed in one bite.
Their texture and size make them ideal for adding texture and flavor to salads, sushi dishes and dips. When cooked, the grapes turn into a delicate airy foam, making them an excellent topping for hot or cold soups and sauces.
Preparation and Serving Suggestions
This is a unique type of seaweed that is popular in Japan and other parts of Asia. They have a slightly salty and crunchy texture and are often served as a side dish. They have a refreshing and delicate flavor with a hint of sweetness and a slight brininess.
Raw
As their name implies, they can be eaten raw and fresh. This is a delightful experience as the lightly salty flavor of the individual fruits plays on your tongue and creates a sensation that resembles popping candy due to the jelly consistency. It’s best to give them a quick rinse before consuming them. Eaten this way, they make a great snack packed with vitamins and minerals such as calcium, magnesium, zinc, and iron.
They also pair well with salads and can be used to add flavor complexity to salsas or other chunky sauces like tzatziki — just cut them into quarters or halves beforehand to make them easier to spoon onto your plate.
Enjoying sea grapes raw allows you to savor their juicy texture while experiencing the combination of floral-salty flavors they provide. If you’re looking for something fun in your lunch box or picnic basket, adding some fresh sea grapes definitely won’t disappoint!
Pickled
Pickling is a popular way to make use of sea grapes—also known as umibudo– and can be stored in your refrigerator for up to a month. To pickle them, start by boiling the sea grapes for 5-7 minutes until they are just tender.
Carefully remove the tops and carefully remove the vine and exposed roots. Thoroughly clean the popsicles before placing them in a large bowl with cold water and 2 tablespoons of white vinegar for 10 minutes.
To make pickling liquid, mix 1 cup of apple cider vinegar, 2/3 cup white or brown sugar, 3 tablespoons salt, 6 garlic cloves (minced), 2 tablespoons black peppercorns (crushed or coarsely ground), 1 teaspoon of each dried thyme leaf and crushed bay leaves together. If desired, add 4-6 slices of red chili pepper to give it more heat.
Once your pickling liquid has been combined well, pour it over your sea grapes so that they are completely covered. Place them in an airtight container and keep them refrigerated for at least 24 hours before serving them for the best flavor results. Pickled umibudo goes great as part of salads or served with sashimi rice balls; however, some people enjoy simply eating them straight from the jar! Enjoy!
In Salads
Since the early 19th century, they have been included in the country’s traditional cuisine and are prized for their unique flavor profile. They have a mild briny taste and are often eaten raw or in salads.
When preparing them for consumption, separate them into strands with scissors and rinse well to remove any impurities. They can then be added to salads either as-is or lightly cooked with vegetables such as bell peppers, mushrooms or onions. Alternatively, sea grapes may be served cold with dressings and delicately folded into lettuce cups with fresh shrimp or salmon for an added touch of flavor.
You can also dress them up by marinating them in lemon juice for 10 minutes prior to serving or by adding condiments like soy sauce and vinegar. For an extra zing of flavor, add a few drops of sesame oil to the dressing.
In Sushi
As a popular ingredient in sushi, they bring a unique texture and flavor to the dish. The small size of their beads means they can be easily added to maki rolls or eaten as an accompaniment to nigiri. Sushi-grade ones are usually lightly boiled or brined prior to serving. This helps to bring out the slight sweetness of the seaweed and makes them easier to chew.
When prepared correctly, they have a crunch similar to caviar, with a hint of ocean brininess — perfect for lovers of seafood with its delicate seafood accent that doesn’t overpower other flavors. They can also be sprinkled on top of sushi dishes after they have been rolled, adding color and texture contrast as well as flavor. They can even be added to hot dishes before cooking — ideal for sushi pizza or soups such as miso soup!
