Hippophae rhamnoides
Intensely sour and a little astringent. The sourness is mostly malic acid and the astringency quinic acid, so most people sweeten it or mix it with other fruit.
Carefully, with thick gloves. The berries cling tight and burst when pulled, so pickers often snip a few laden twigs, freeze them, and knock the frozen berries off into a bowl.
Male and female flowers grow on separate shrubs, and only the females fruit — with a male close enough to pollinate them.
On coastal dunes and cliffs around the North Sea and Baltic, on river gravels in the mountains, and on dry slopes from the Carpathians east. In Britain it is native on the east coast of England and planted elsewhere.
