Our grandparents would have recognized it immediately. It’s a small, unusual and almost forgotten fruit, which many people today have never tried. I’ll explain what it is in the first comment

Light but nutritious fruit
Gooseberries contain about 44 calories per 100 grams. The same amount also contains fiber, potassium, vitamin C, and small amounts of calcium, magnesium, and iron. Therefore, they are the perfect fruit for those looking for something fresh, low in calories, yet rich in nutrients.
The taste is not very sweet: it tends towards sour, especially if the fruit is not fully ripe. This makes it a favorite among those who prefer berries with a more intense flavor and less sugary texture.
How to eat
Gooseberries can be eaten fresh, when fully ripe, or used to make jams, jellies, syrups, desserts, and fruit salads. Their slightly tart flavor also makes them an interesting addition to savory dishes, salads, or sweet-and-sour dishes.
It is best to avoid consuming unripe fruit, as it can be difficult to digest and cause intestinal discomfort. People who suffer from diverticulosis or have sensitive stomachs should be careful, as the tiny seeds found in the berries can cause discomfort.
Why rediscover it?
Gooseberries are an almost forgotten fruit, but they deserve a return to our tables. They are fresh, light, rich in fiber and antioxidants, and can be an interesting alternative to traditional berries.
It is not a miracle food, but when included in a varied diet, it can contribute to the well-being of the gut, skin, and body in general.
