Vaccinium vitis-idaea!!

No, it's not a spell you'll learn at Hogwarts but it is something pretty magical in its own right. It’s the partridgeberry (aka lingonberry or cowberry) — a beautiful tart, bright red fruit that grows right on the ground. The magic doesn’t end with the taste and colour, partridgeberries are pretty amazing from a health/antioxidant standpoint. They give you plenty of manganese (a component of antioxidant enzymes), supply vitamin E and C (both of which also function as antioxidants), and their red colour comes from anthocyanins, which is thought to have antioxidant benefits. (Read more here.)

Partridgeberries are used in puddings, quick breads and cakes but I think they really shine in jam. I have very happy childhood memories of eating fresh, homemade bread topped with partridgeberry jam and canned Fussel’s-brand cream. So very good.

And partridgeberry jam is my absolute favourite filling for homemade jam-jam cookies.

Here's a quick recipe for a small batch of jam.

Sadly, I understand that partridgeberries are scarce this year. One more piece of less-than-good news, in a year of less-than-good news (2020 can take a break anytime now).

In a pinch, I sometimes use cranberries. They are similar but not the same.
