Yup, Blackthorn. Big spines,

Yup, Blackthorn. Big spines, small leaves, blue berries this time of year. If you rub the berries the blue powder comes off, leaving a shiny almost black berry.

When I was a kid -

we called them "wintercracks".
Fill a bottle 1/3 full of sugar, add the same volume of sloes (pricked all over with a pin), top up with gin. Stopper and leave for at least a month. Enjoy - but - carefully.

if dried blackthorn is one of

if dried blackthorn is one of the best firewoods you can get in this country and dose burn like coal. be careful when handling blackthorn as cuts from the spines will almost always get infected. it is thought that this is either because of the shape of the thorns, some sort of substance secreted by the plant itself or, most likely, that the spines provide the ideal conditions for certain bacteria or fungi to live in. when making sloe gin it seems to work best if you prick the berries with spines from the plant as opposed to a pin but no one knows why. furthermore sloes are best picked after they have had a couple of decent frosts on them.
