The sea grapes seem to almost explode in the mouth releasing a unique flavor of the sea!

Each bag ordered contains 100g/3.5oz dehydrated Umibudo algae which yields about 500g/1 pound of fresh sea grapes once soaked.

This kind of seaweed can reach up to 5 meters in length but only the extremities including the so called “sea grapes” are consumed.
Here in Okinawa, Japan we harvest our sea grapes where they have been enjoyed for eons. Sea grapes are usually eaten raw with vinegar, as a snack or in a salad. You can enjoy them raw with soy sauce or rice vinegar mixed with mustard.

In search of other secrets of nature, we have found in Japan: Green caviar! Sea water plants with the highest nutrient density from the genus of Caulerpa Lentillifera algae, a natural seaweed – algae, which is cultivated, cultivated and processed in Japan.

Due to their exceptional surface, these aquatic plants can absorb valuable nutrients such as amino acids, mineral salts, trace elements, vitamins, polyphenols and flavonoids from the seawater and – in comparison to terrestrial plants – store up to 1000 times higher concentration.

In Japan, this algae is a delicacy and makes for a fantastic decoration. The sea pearls/sea grapes are eaten fresh, dressed as a salad or simply as a snack in between. They slightly taste like seaweed and have a consistency like real caviar, a crisp freshness kick when eating the natural sea grapes is guaranteed.

Recipe Ideas

Before serving, lightly wash the sea grapes to remove the sea water and soak them for a couple of minutes in water at room temperature. Sea Grapes are eaten raw and can be served in a variety of ways. A popular idea is to dip them in soy sauce and wasabi as you would do with sushi. It can also be added to the top of a salad, making it an exotic dish.

Placing your sea grapes in fresh ice water for a couple of minutes will make them even more crunchy without any “fishy” smell, a very refreshing snack unlike the “nori” seaweed you might know from sushi. Take the now crunchy green sea grapes out after a couple of minutes and enjoy!

How do you prepare green caviar sea grapes?

Step 1: Take the sea grapes out of bag, then put them in clean water for around 5 minutes. Your sea grapes will start to soak in the water, refreshing themselves basically and expanding in size 5-fold. Rinse your sea grapes in clean, cold water twice, each time for 5 minutes.

Step 2: Directly eat sea grapes with sauces you love. They go very well on their own with soy sauce, lemon juice, wasabi, mayonnaise, chili or with cold salads or when used in cooked dishes.

Recommended as crunchy salad booster, snack, appetizer, canapé, antipasti, entree, hors d’oeuvre or a decorative sideboard.

Basically unknow outside of Japan sea grapes make an awesome addition to any salad!
