Make breakfast extra special with homemade jam. Whether you prefer toast, croissants or crumpets, this Mandarin Jam is the perfect accompaniment. I can certainly vouch for the croissant and Mandarin Jam option.The original Mandarin Jam recipe is dated July 1941 and contains 9 cups of sugar. Whoa! But after checking other recipes, I discovered the fruit to sugar ratio was correct. I did, however, halve all the quantities because 9 cups of sugar sounded like an awful lot of jam. I still ended up with 3 medium jars of jam after halving the quantities.So, ready to jam?

Mandarin Jam: tips for getting it right

Sterilise jam jars by placing in the dishwasher on the hottest cycle and allowing to air dry.

This recipe calls for 1 1/2 cups mandarin, which is roughly 5-6 medium mandarins. I used Imperial mandarins since they are readily available and have very few seeds.

The trickiest part is working out if the jam has jellied. Check out this explainer video for simple ways to test your jam.

Have some Jamsetta on hand. If your jam fails to jelly, this will give it a helping hand.
