PREPARE: Halve and de-stone the peaches, then cut into 1cm (½ in.) chunks. Cut a deep cross in the bottom of each of the tomatoes, place them in a heatproof bowl and for over boiling water to cover. Allow to sit for 1 minute, then refresh under cold water. Peel off the tomato skin, and discard. Chop the tomatoes roughly, halve and finely dice the onions, then peel and finely dice the ginger.

BRING TO BOIL: Put the peaches, tomatoes, onions and ginger in a large, heavy-based, stainless steel or enamel saucepan. Pour over the vinegar and stir in the sultanas, mustard seeds, cumin, salt, chilli and pepper. Bring the mixture to the boil over medium heat.

SIMMER: When the mixture begins to boil, turn the heat down and simmer for 30 minutes, stirring occasionally to prevent the chutney from catching on the bottom of the pan. The fruit should soften, but you should still see visible chunks of peach.

STERILISE JARS: Meanwhile, wash four 350ml glass jars in hot soapy water. Put them in a baking dish and heat them in the oven at 120°C / 250°F / Gas mark 1 to sterilise. Put the lids in a heat-proof bowl and pour over boiling water.

ADD SUGAR: When the fruit has softened after 30 minutes, pour in the sugar and stir well until dissolved. You’ll notice the chutney has become beautifully glossy. Turn the heat to medium and simmer for 15 minutes, stirring often to prevent the chutney from burning.

LADLE INTO JARS: After 15 minutes when the chutney has reduced and thickened, remove from the heat. Ladle or pour the chutney into the hot, sterilised jars. To make life easier I recommend a jam funnel as it makes the task of pouring the chutney much easier. Make sure the rims on the jars are clean and free of any chutney, then seal with the lids and leave to cool.

COOL AND STORE: When the chutney has cooled, clean the jars if necessary, label clearly with the type of chutney and the date (you would be amazed how easy it is to forget what is in one of these jars) and store in a cool, dry place. You can eat the chutney immediately but it will improve over a couple of weeks.
