You will need to start preparing this dessert the day before the birthday party, picnic, or event that you are making it for.
Begin by dissolving each pack of jelly into 250ml of boiling water. Ensure that you do not follow the instructions on the jelly packet as the terrazzo jelly needs to be more concentrated to create a firmer texture.
Pour each mixture into a separate tray with the jelly no more than 2.5cm deep. Our enamel serving trays
or square bake trays
are a great size for the jelly to set in.
Place the trays of jelly into the fridge and allow to set for 2-3 hours.
Carefully cut the jelly into small cubes using a sharp knife.
Next, dissolve the packet of unflavoured gelatine in 500ml of hot water. Allow this mixture to cool and then whisk in the can of sweetened condensed milk.
Leave this mixture until it is completely cool to the touch.
Place the colourful cubes of jelly in an even layer in the square bake tray
and then pour over the condensed milk mixture. This is a child-friendly step and allows your children to use their creativity to design a colourful pattern.
Cover your enamel square bake tray
and leave it to chill in the fridge overnight.
Cut into squares and serve to your party guests!
