Other species of rasps are the omson raspberry (Rubus strigosus) and the black raspy (Rbus occidentalis), which is called the western raspy. Their tastes are similar to the classical red variety.

While fresh raspberries offer peak nutritional value, homemade preserves—such as jams, confitures, and fruit syrups—preserve their benefits for winter. Recipe for homemade raspberry jam: Ingredients include 2 kg of fresh raspberries, 600–800 g of cane sugar or xylitol, and the freshly squeezed juice of one lemon. Combine the berries with the sweetener and rest for 2 hours to release juices. Simmer gently over low heat for 30–40 minutes while stirring until thickened, then blend in the lemon juice. Ladle the hot jam into sterilized glass jars, seal tightly, and pasteurize in a water bath for 15 minutes. Store in a cool pantry.
How many calories do raspberries contain?
Raspberries are exceptionally low in calories: 100 g of fresh berries provides merely 52 kcal. They supply nearly 6.5 g of dietary fiber, making them one of the finest natural tools for digestive regularity and satiety.
