*The saucer wrinkle test basically requires you to put about 5 saucers in your freezer when you begin making your jam. Once you think the jam might be ready then you can double check by removing a saucer from the freezer, dropping a teaspoon of jam on it then placing the saucer in the fridge. After about 30 seconds remove the saucer and push the jam with your finger. If it wrinkles up it’s ready, if it just pools back into the space your finger has left then it needs more bubbling time. Boil it a bit longer, then test again with another saucer.
*To sterilise the jars place the very clean jars you would like to use in an oven pre-heated to 140°C for 20 minutes. Sterilise the lids by dropping them into a saucepan of boiling water for 10 minutes with a splash of vinegar. I don’t sterilise my lids in the oven as they tend to ruin.
