They couple would trudge along to markets and fairs for a few years raising money until ill health took its toll a few years ago and making preserves for fundraising was put on hold.
But when Mr Clarke died last year Mrs Clarke began making preserves again and this week Katherine Trass from St John Cadets picked up 420 jars of produce to be sold at the fair.
Not bad considering the former teacher had to put an advertisement in the newspaper calling out for windfall plums after someone helped themselves to the fruit under her brother's tree, which she normally used.
"I forgot this is Masterton and people can be so generous. I've had plums coming out my ears since," she said.
Sadly, though Mrs Clarke isn't able to keep making the preserves because of her health, so will start supporting children by knitting dolls to go under the community Christmas tree for those who otherwise wouldn't get a gift from Santa.
"It's for the kids," she said.
