Mango and Strawberry Jam

3 mangoes, peeled, seeded and diced
250 gm punnet of strawberries, hulled and quartered
1 3/5 cups sugar
Juice 1 lemon

Directions

In a heavy- based saucepan, combine mangoes, strawberries, sugar and lemon juice. Cook over moderate heat stirring to dissolve sugar. Bring to boil and simmer 30-45 minutes until the jam is thick. Test that the jam has set by placing a small drop on a cold surface. The jam is ready if it forms a skin. Pour into hot sterilised jars and seal with sterilised lids. Store in a cool place.

[ Cook's Comments - boil and simmer uncovered or the jam will not set ]
