The park is full of ripening blackberries, all free from the contaminants of vehicle exhaust. Here is a recipe for blackberry and apple jam.
It suggests using frozen blackberries so that you can make jam at any time of year, but it works even better with fresh blackberries. Try it.
UPDATE: there are apple trees on council land around Trowbridge of which the council says, “people are welcome to collect windfall apples in public open spaces.”
So. . . . pick your blackberries in the park and your apples from the big roundabout on Bradley Road.

My Mum used to make all her own jam, gooseberry was always our favourite but all home made jam is delicious when you are hungry children.
Blackcurrants! We children got the tedious job of picking out the stems and leaves but the jam was wonderful.
I know what you mean, when I was a child there were no frozen peas – there were no domestic freezers! My sister and I had the tedious job of shelling peas from their pods when my Mum came back from a day pea-picking on the nearby farm. They too tasted good,as the rest of the year we had to make do with tinned peas!
