First, cut the tomatoes, onions, raisins, and finely chop the garlic.
Next, put all the chopped things into a pan made of steel. Heat it until it starts bubbling and boiling.
After that, lower the heat. You should see tiny bubbles, but don't cover the pan. Sometimes give it a little stir.
Wait for the chutney to become thick and turn brown. That's when it's done and ready to eat.
Get some warm, clean jars ready. Carefully put the chutney into these jars. Close the lids really tight to keep it fresh.
If you have empty jars from the store, you can wash them and use them again. Just remember, don't use jars with lids that have metal parts.
It's safer to use special jars for canning. These jars have lids that are not made of metal, either they're coated with plastic on the inside, or they have two-part lids.
Before you put the chutney in, make sure the jars are clean. You can do this by putting them in water to wash them.
Then, you need to put the jars in boiling water for about 10 minutes. This helps to make sure they are very clean.
As the jars cool down, you'll hear a popping sound. This means the lids are sealing shut. Let them sit like this for about 12 hours.
Once the jars are cool and sealed, it's a good idea to put labels on them. After that, keep them in a dark place like a cupboard.
If you open a jar to use some chutney, put the jar in the fridge. Try to use up all the chutney within a year.
