My current plan:
1 - purchase several pounds of fresh blueberries, plums, and apples, along with a bag of sugar and a few savory ingredients.
2 - spend a day stirring pots of various combos of above substances, before placing in jars and sealing.
3 - enjoy the hell out of blueberry/apple jam, spiced plum preserves and spicy blueberry chutney with breakfasts, on sandwiches and with cheese.
Optional step 4:
Send jars to friends and family, so as to avoid eating all of it myself and gaining two stone.
I'm currently back on step two, as the jars of blueberry/apple jam were my test case last week. After trying the final product on cornmeal waffles, I added the potential fourth step. It's not safe to keep too much close at hand.
