Combining My Two Favourite Berries
I had been looking for a foolproof, delicious recipe to combine two of my favourite fruits: strawberries and raspberries. I played around with the proportions and managed to create something that has gone straight into my go-to recipe book! I have handed out jars of this jam to the great delight of my friends. It is beautifully sweet and was particularly delicious served on freshly baked scones right out of the oven.
In addition to the recipe below, I have included advice on sterilising jars and some other useful tips you might find useful. Enjoy!
|Prep time||Cook time||Ready in||Yields|
3 (300ml) jars
- 500 grams strawberries, chopped and hulled
- 250 grams raspberries
- Rind and juice of 1 lemon
- 670 grams granulated sugar
- Add your strawberries, raspberries, lemon rind and lemon juice to a large-capacity pot. (Try to avoid aluminium pots where possible. Aluminium coated in Teflon should be fine.)
- Cook slowly until all of the fruit has broken down into a paste-like consistency. The time for this will vary depending on how ripe and firm your fruit is. I help it along towards the end by using a potato masher to get rid of big lumps.
- Add the sugar and stir over a low heat until the sugar has dissolved completely.
- Bring to the boil, then boil rapidly. Stir constantly.
- After 10 minutes, test for set. Do this by placing a plate in the freezer before starting. When you're ready for the test, take the plate out of the freezer and take the jam off the hob. Use a spoon to blob a little bit of jam onto the plate. Wait a few seconds and push it with your finger. If the jam is sticky and forms a skin, it is set. If it is runny, return the pan to the heat for another 5 minutes and test again.
- Take the jam off the heat and use a wide-mouth funnel to pour your jam into sterilised jars (while the jars are still warm to eliminate the chances of the glass cracking).
- Fill the jars almost up to the brim, seal with lids immediately and leave to cool.
- Sealed jars may be stored at room temperature. Once you open a jar, however, it should be stored in the fridge.
Sterilising Jars and Extra Tips
It is very important to sterilise your jam jars before use. This ensures that your jam stays fresh for as long as possible. I sterilise my jam jars by first washing them (and their lids) in very hot soapy water, then rinsing with boiling water. I then place them upside-down on a clean baking sheet (covered in greaseproof paper) and put them in a preheated oven at 120 °C (250 °F). The jars stay in the oven like that until I am ready to put the jam into them.
I then take out the jars one by one (wearing oven gloves) as I need them and fill them up. I use oven gloves to put the lid on the jar as soon as it is full and then place it upside down on a towel, before taking out the next jar. The jars I use are very reliable, and I love the twist lids. I've even been told that they look professional enough to sell, so I recommend them.
I don't have a wide-mouthed funnel, so instead, I use a milk jug with the bottom cut off. I invert it over the jar, holding on to the handle, and pour into the missing 'bottom', the jam then comes out of the mouth of the jug into the jars.
I also find it very helpful to put down a towel throughout this process for any little stray blobs. Then I can throw it in the wash and avoid spending time scrubbing at my countertops.
