From the NYT:

That meant Labour-held seats were ripe for the picking, especially since northerners were not enamored of Mr. Corbyn, 68, a far-left urbanite. He seemed weak on defense and security, shaky on economic management, passionate about places like Venezuela and Nicaragua, had once had strong sympathies for the Irish Republican Army and liked to make jam.

Jam? Jam tho? Don’t northerners make loads of jam? Are they too tough because putting up fruit is for the weak? It’s actually a reasonable amount of trouble, even if very worth it.
