making rhubarb -strawberry marmalade

Now is everything growing so well in our vegetable garden. After a long period with warm and dry weather, have we got some rainy days now. You hear and see the vegetables grow 

J. We have got a lot of strawberries this year and the rhubarb plant is also growing very well, so I thought it would be nice to make some marmalade. This is my recipe:

I picked about 1kg strawberries and 600gr rhubarb. Wash it well and cut the rhubarb in 1/2cm pieces. Boil the rhubarb pieces in a little water, 3-5min. take it from the fire and mix the marmalade sugar (1,5kg) and the strawberries in. Replace the pan on the fire and bring the mixture to a boil. Stir frequently and boil it 5 min. Now the marmalade is ready, pack the marmalade into the jars, turn on the lid, turn the jars upside down en let they cool.
