Jam-making is a great way of using imperfect fruit. The odd mark here or there on the skin doesn't hurt, as long as the fruit is free of soft spots. This jam is relatively low in sugar; traditional versions usually have equal quantities of sugar and fruit, but we've nearly halved the amount. This makes for a softer set and a shorter shelf-life, but brings the taste of the apricots to the fore. Store the jam in the fridge rather than at room temperature - it will last a couple of months if you can keep your hands off it. We love it on buttered sourdough toast, especially with ricotta.
