easy mixed berry mousse made with uncooked raspberry jam

Fruit and dairy products make a delicious combination and chilled desserts using these ingredients can easily be assembled for quick summer entertaining. This months blog hop theme “Berry Nice to Meet You” found me scouring the supermarkets to find the freshest raspberries (organic if possible) available, as I wanted to make an uncooked raspberry jam. I love traditional jam making and had recently made some delicious Doughnut Peach Conserve, but it’s always nice to try a different method!

Planing an easy make-ahead dessert for entertaining, the uncooked raspberry jam was perfect for this easy berry mousse, assembled and served in glasses. Actually this berry mousse would make a wonderful filling for pavlovas, meringues and cakes.

When making the jam, warming the sugar makes it easier to dissolve and the heat helps release some of the pectin when mixed with the berries! Infusing the warming sugar with the wonderful perfume of thyme had more of a therapeutic effect on me than the taste it delivered. However the fresh thyme served with the finished mousse was really quite delicious…!

Using only sugar and raspberries in equal weights, Marguerite Pattens version of uncooked raspberry jam; heat the sugar for 15 minutes in an oven on a low temperature  before mixing with the berries until the sugar has dissolved, then place the jam into hot jars and store in the fridge. I would imagine using perfectly ripe berries would make a nicely set jam but I needed to give my jam a little helping hand by adding a small amount of gelatine.

Over at Serious Eats you can find different recipes for delicious uncooked jams or freezer jams (method of preserving), which use instant pectin for sure jam setting results. Less sugar and more fruit is my preference when making jams and conserves, I still find them very sweet… but also berry very delicious!

Room temperature does make this jam somewhat runny, so when serving this jam with freshly baked scones, I would leave a little pot resting on some crushed ice, keeping its spoonable consistency.

Uncooked Raspberry Jam


  • 100g castor sugar
  • 5 sprigs of fresh thyme (optional)
  • 170g fresh raspberries or blackberries or you could even use a mix
  • 1 tablespoon lemon juice
  • 1/2 teaspoon powdered gelatine

How to make: Place the sprigs of thyme into a heatproof bowl and cover with the castor sugar. Place the bowl into the oven and turn the temperature to low (160°C), leaving the sugar to heat and infuse with the flavour of thyme for about 30 minutes, give a quick stir half way through heating.

While the sugar is warming place the raspberries into a bowl. Remove the hot sugar from the oven, discarding the thyme. Quickly sieve (catching any small bits of herb) over the raspberries. Gently mix together and set aside while preparing the gelatine.

Pour the lemon juice into a small heatproof dish and sprinkle over the gelatine, leave to sponge for a couple of minutes. Bring a small amount of water to a boil in a small saucepan, remove from heat and place the bowl containing the gelatine into the hot water. Stir the gelatine until completely dissolved.

Gently mix the raspberries and sugar a few more times, ensuring the sugar has melted. Stir the gelatine into the raspberry jam. Spoon the raspberry jam into a suitable jar rinsed with some boiling water, cover and leave the jam in the fridge to set, a few hours or overnight.

When making and assembling this dessert certain kitchen tools help with getting the job done faster… using an electric whisk to beat the cream and piping the berry mousse into the serving glasses using a piping bag fitted with a plain tipped nozzle.
