Ingredients
Serves: 20 

  • 500 g strawberries or raspberries
  • 50 ml lemon juice
  • 500 g jam sugar

Method
Prep:1min  ›  Cook:20min  ›  Ready in:21min 

  1. Put the strawberries in a large, microwaveable bowl with the lemon juice. Cook on full power for 4 minutes, or until the fruit is soft.
  2. Stir in the sugar and when completely dissolved, cook for 15–20 minutes, stirring every 3 minutes.
  3. To test when the jam is ready, after 15 minutes, spoon a little jam onto a chilled saucer, cool for a few seconds then push a finger across it. If the surface wrinkles, it has reached setting point, if not, cook the jam for a further 3 minutes, then test again. Continue testing every 3 minutes until setting point is reached.
  4. Stand for 5 minutes, then pour into warm sterilised jars, seal and label.

COOK SMART

*Cooking time will vary depending on the power of the microwave and ripeness of the fruit. *Jam sugar contains a balanced amount of natural pectin and citric acid, which overcomes the problem of setting encountered with some fruits, like strawberries with low pectin levels. You can therefore be sure of a perfect set.

I had never made jam before so I thought I'd use this recipe as it seemed easy in the microwave. I decided to half the ingredients in case it didn't work (because I've never made it). When I was cooking it in the microwave, I had to stir it every 1 minute because it kept overflowing in the bowl. I suggest that if you are going to use this recipe, you'll need a very large bowl. Apart from that, it was a good recipe, easy to follow. - 01 Jun 2013
