Raspberries love the Scottish climate (lots of rain!). The plump, juicy berries carry on ripening even on the most dreary of summer days. I have been picking my raspberries since the end of last month. Sadly, it looks like the end is nearly nigh; the supply is dwindling, but there are still enough to bag up for the freezer for later in the year, and then I will leave the rest for the blackbirds!
The bushes in the garden are now in their twelfth year, and have given me a good harvest every season. However, I think this autumn, it will be the time to plant some new canes. The variety I chose to grow is Glen Ample; selected for the large-sized fruit, and as the label said at the time, “perfect for cooking and jam-making”. And, they have certainly proven to be.
If you’ve never made jam before, raspberry jam is the easiest to make. It practically sets as soon as the fruit and sugar boils. Frozen raspberries work equally as well for jam-making; whilst other fruit loses pectin (the natural setting agent found in many fruits) after freezing, I have found little difference in setting jam made with the frozen berries.
I have 3 methods for making my raspberry jam, depending on how much fruit I have picked, and how much time is available. The first method, is the traditional saucepan method, great if you have a large amount of fruit and a bit of time. This method works well with frozen berries – just let them thaw out in the saucepan you’re going to use to cook them in so that none of the juices are wasted.
Traditional raspberry jam – use equal amounts of prepared fresh (or frozen) raspberries to granulated sugar. The yield is approximately the same as the weight of the 2 ingredients combined, so 500g raspberries and 500g sugar should give you 1kg of jam.
Heat the fruit by itself in a clean, large saucepan, stirring, until it steams and starts to break down. Mash it a little with a wooden spoon, reduce the heat and stir in the sugar. Heat, gently, stirring, until the sugar is completely dissolved, then raise the heat, bring the jam to a rapid boil, and stop stirring. Cook for 2 minutes. Turn off the heat and let the jam settle for about 5 minutes. Stir, and then transfer to clean, sterilised jars whilst still very hot. Seal immediately. Cool and label. In a cool, dark, dry cupboard, this jam will keep unopened for up to 12 months. Store in the fridge once opened, and eat within a month.
Microwave raspberry jam – super-speedy; hassle free; the perfect jam method for smaller amounts of fresh berries (I haven’t tried this with frozen berries but I can’t see why it wouldn’t work). Use finer, caster sugar for this jam as it heats and dissolves more quickly. The jam has a good set, and I find the colour is brighter than the traditional method; the flavour is much the same. My microwave is 900W so you may need to adjust timings accordingly.
Wash and pat dry 250g prepared fresh raspberries and mash with a fork in a large, perfectly clean microwave-proof bowl ( the mixture needs room to boil in the microwave, so choose a good size to prevent the mixture boiling over).
Put 250g caster sugar in a microwave-proof bowl and cook on Medium for 10 minutes, stirring every 2 minutes. The temperature of the sugar should be around 80°C (I use a food probe to check). Carefully pour the sugar over the mashed raspberries and stir well – the mixture will be very sloppy at this stage.
Put back in the microwave, and cook on High for 3 minutes to reach boiling point, then boil for 2 minutes. The jam is now ready to put in jars and seal as above. The jam has the same keeping qualities as with the traditionally made jam above.
My third method for making jam is probably the most delicious and it involves no cooking of the raspberries at all. You do need to select the perfect, unblemished, fresh specimens for best results, and wash the berries well before using. Use caster sugar for speedier heating and dissolving.
This fresh jam has a much softer texture than the other 2. You need to store it in the fridge – I find it keeps well for 4 to 6 weeks. It also freezes so you can keep it for longer and then take out small portions as and when you fancy. If you haven’t got a microwave, you can heat the sugar in a saucepan – just keep the heat very low and keep stirring the sugar so that it doesn’t melt or burn.
Fresh (uncooked) raspberry jam – wash and pat dry 250g prepared, unblemished, very fresh raspberries and mash with a fork in a large, perfectly clean, heat-proof bowl. Sit the bowl on a clean tea-towel.
Put 250g caster sugar in a microwave-proof bowl and cook on Medium for 15 minutes, stirring every 2 minutes. The temperature of the sugar should be around 120°C (I use a food probe to check). Carefully pour the hot sugar over the mashed raspberries and stir well – it will hiss and steam. Cover loosely and leave to cool completely, then spoon into clean, sterilised jars or containers. Seal and label, and store in the fridge or freezer.
