Lemon Curd Crumble Slice

Don’t assume that this is fiddly to make – this slice is very quick and easy to create in the Thermomix and the result is divine (especially if you are a lemon curd addict like me). I have also made a great apple version of this slice – simply replace the lemon curd layer with steamed apple slices.
This is lovely served warm with custard as a dessert or eaten as a slice. It is very easy and gives a very impressive result.

Lemon Curd
  1. Place all ingredients into the Thermomix bowl and cook at 100 degrees for 5 minutes on speed 4 (tip: when squeezing lemon juice leave the MC in place and squeeze directly onto the lid, the juice dribbles in the bowl but the MC catches the pips)
  2. Remove from bowl once cooked and set aside (it may look runny at this point but it will thicken slightly on standing)

  1. Preheat oven to 180 degrees
  2. Lightly grease and line a lamington tray with baking paper - extend the paper 2m above both long sides.
  3. Place butter into Thermomix bowl and melt at 60 degrees, 2 minutes, speed 4.
  4. Add dry ingredients and egg. Beat 30 seconds, speed 5.
  5. Press half the mixture into prepared tin (use the base of the MC to smooth it in)
  6. Cover the base with the lemon curd (then lick the bowl yum!)
  7. Crumble the remaining mixture over the top, it doesn't matter if the crumble is not perfect, rustic is good!
  8. Cook for 35-40 minutes or until golden on the top.Cool in the tray and then slice into even squares.
