How to choose sea grapes

When choosing sea grapes, look for clusters that are plump and vibrant, with a bright green color that indicates freshness. The texture should be firm to the touch, as soft or mushy grapes may signal overripeness or spoilage.

Avoid sea grapes that have dark spots or a dull appearance, as these can be signs of aging or poor quality. Additionally, the aroma should be briny and oceanic, reflecting their natural habitat; any off-putting smells may indicate that the grapes are no longer fresh.

How to store sea grapes

To properly store sea grapes, keep them in a cool, dry place, ideally in the refrigerator. Refrigeration is crucial for maintaining their freshness and preventing spoilage. Place them in a breathable container, such as a mesh bag or a paper towel-lined bowl, to allow for air circulation while keeping moisture at bay. The optimal storage temperature is between 32-40°F (0-4°C).

Avoid exposing sea grapes to direct sunlight or high temperatures, as this can degrade their quality and flavor. It's essential to consume sea grapes within a few days of purchase for the best taste and texture, as they are highly perishable. If you notice any signs of wilting or discoloration, it's best to discard them to ensure food safety.

✅ Extra Tip

To enhance the flavor of sea grapes, try lightly sautéing them with garlic and olive oil before adding them to salads or seafood dishes for a delicious umami boost.

How long does it last?

Sea grapes, also known as Caulerpa racemosa, are a type of edible seaweed that can last for a short period if not stored correctly. When harvested fresh, they are best consumed within 1-2 days for optimal flavor and texture. If you need to store them, keeping sea grapes in a sealed container in the refrigerator can extend their freshness for up to 1 week. However, they should be rinsed gently and kept moist to prevent drying out. For longer preservation, sea grapes can be blanched and frozen, which can help them last for several months, although this may alter their texture. Proper handling and storage are essential to enjoy their unique taste and health benefits.

What to do with leftovers?

Leftover sea grapes can be a delightful addition to various dishes, enhancing both flavor and nutrition. Toss them into salads for a briny burst of flavor or use them as a topping for rice bowls to add a unique texture. They can also be blended into smoothies for a nutrient-rich boost or incorporated into salsas for a refreshing twist. If you have a surplus, consider making a sea grape pesto by blending them with nuts, garlic, and olive oil for a delicious spread. Additionally, sea grapes can be pickled to create a tangy condiment that pairs well with grilled meats or seafood. For a creative snack, try mixing them with cream cheese or yogurt for a savory dip that complements crackers or fresh vegetables.
