Peach and verjuice jelly

1.Combine peach, verjuice, apple, lemon juice and seeds and 1 litre water in a large saucepan and simmer, stirring occasionally, over medium-low heat for 1 hour. Strain through a sieve double-lined with muslin into a large bowl to yield 1 litre (discard pulp). Transfer to a large saucepan, add sugar, stir over low heat until sugar dissolves. Increase heat to medium and simmer until jelly reaches setting point (45 minutes-1 hour). To test jelly, place a spoonful on a chilled saucer and leave to cool. Push jelly with fingertip, if it wrinkles it’s ready. Skim scum from surface and ladle into sterilised jars. Add a thyme sprig to each jar, seal and invert for 2 minutes, then turn upright and set aside to cool completely. Jelly will keep refrigerated for up to 3 months.
