How to Make It
In a small saucepan, combine the vinegar, water, sugar and mustard seeds and bring to a boil to dissolve the sugar. In a heatproof bowl or jar, cover the apricots, raisins and bay leaf with the hot brine. Let cool to room temperature, then cover and refrigerate overnight or for up to 1 month. Just before serving, coarsely chop the apricots.
