Raspberry Blancmange Technical Challenge

Dessert week took a trip back in time with the raspberry blancmange technical challenge. Apparently a favorite from the 70s, this gelatin-based dessert is smooth and creamy with just a bit of a wiggle.

Not everyone in my house is a fan of gelatin-type desserts so I only made a half batch of Prue’s recipe. For the full recipe, visit the GBBO website. My one change is upping the sugar content by 33 percent because the first batch was a bit bland following the recipe as is.

Raspberry Blancmange Recipe

Makes 8 2.5-inch round molds

  • 2 tsp powdered gelatin (1 sachet / 4 gelatin leaves)
  • 375g fresh raspberries
  • 25ml raspberry liqueur
  • 12.5g cornflour (corn starch)
  • 150 ml milk
  • 100g sugar (caster – UK / granulated – US)
  • 20g ground almonds
  • 1/2 tsp almond extract
  • 225 ml heavy cream


  1. Bloom the gelatin dissolving the powdered gelatin in twice the amount of water or by soaking the leaves in cold water, and set aside for 3 – 5 minutes.
  2. Puree the raspberries then run through a sieve to remove the pips.
  3. Dissolve the cornflour / corn starch with a little of the milk in a medium pan. Add the remaining milk, along with the sugar and ground almonds. Put heat on med-high and bring to a boil. Reduce heat to med-low and simmer gently for 3–5 minutes to thicken. Remove the pan from the heat.
  4. Add gelatin to the milk mixture and dissolve. Add in 150 ml of heavy cream, almond extract and raspberry puree, and stir to combine.
  5. Pour into molds and set in the fridge to chill for at least six hours.
  6. When ready to serve, whip the remaining cream on high until you get stiff peaks. Spoon into a piping bag with a star tip / nozzle. Pipe decorations as desired.

I love eating carbs, feeding people and watching the Great British Bake Off (aka in the US, the Great British Baking Show). I'll be chronicling my attempts at all the challenges per GBBO season.

  2. Omg, these are literally making my mouth water! I love the sweet tartness to raspberries and it looks like it would pair perfectly with that whipped cream topping!
