  • The jelly referred to in the ingredients list is for the concentrated jelly products available in the UK that need dissolving in water in order to make standard jelly. If you live in North America, you can substitute it with 85g (3oz) packet of powdered strawberry jello. If you are using the latter, omit the step of dissolving the jelly in a bit of water first. Simply sprinkle the jello, along with the sugar, on the rhubarb proceed with the cake mix.
  • The cake mix should be enough to make a two-tiered cake.
