Peel and core the apples
Peel the onions and prepare the other fruit and veg you are using.
Chop all fruit and veg in a food processor, or by hand, depending on your level of patience.
Transfer the fruit and veg to a large pot, add the vinegar, sugar, and spices.
Stir well with a wooden spoon, and bring the mixture to a boil. Reduce the heat to medium-low, and simmer, stirring regularly, until the mixture reaches a jam-like consistency—approximately 90 minutes.
When your chutney has thickened and your jars/lids are sterilized, bring everything over to a cleared space in your kitchen to start jarring.
Using a clean stainless steel ladle or serving spoon, carefully spoon the hot chutney into the jars almost to the top—making sure to keep the rims of the jars clean. If any chutney drips onto the jar rim, simply wipe it clean with a tea towel. A stainless steel jarring funnel is helpful here, but if you don't have one, you just need to be extra cautious.
Once the jars are filled, screw the lids on tightly. You should start to hear them pop as they seal naturally over the course of an hour or so.
Store in a cool dark place until ready to enjoy!
