I love my job, this is what I did yesterday in preparation for my Halloween Whizz Bang workshop tomorrow. These take around 20 minutes to set due to use of Gellazoon or Gellan Gum, a molecular gastronomy powder which makes instant setting jelly. If you don't have any of this in your kitchen (!) then you can use agar agar which sets pretty quickly or gelatine*. If using gelatine you'll need to make these over 1-2 days to allow setting time. The brain jelly moulds are bought from Amazon and they work really well. The YouTube version is here.
makes 4 jelly brains
200ml strawberry milk
4 flat scoops of gellazoon or 2g Gellan Gum
Heat the milk and gellazoon or gellan in a saucepan, stirring constantly, until it boils. Remove from the heat and half fill the brain moulds. Leave for 5 minutes or so until set, keep the milk warm or it will set. To set quicker place the moulds in ice water.
Once set place half a teaspoon of raspberry jam in the centre of the jelly brains and carefully top up with the rest of the milk. Leave for 10 minutes or so to set.
Turn out onto a plate, and brush with a little extra jam to create and gooey effect on the brain.
* if using gelatine use half the quantity of milk. Dissolve the sheet gelatine (check instructions for correct quantities to use) in the strawberry milk and half fill the moulds as before. Leave overnight to set. Add the jam and make up the rest of the milk and gelatine and fill up the mould. Leave to set overnight.
