The Method Enter Bake mode

  1. Classic mode Step 1

    To make the base, place the biscuits in a plastic bag and bash with a rolling pin to make fine crumbs. Melt the butter in a pan and stir in the biscuits.

    Ingredients for this step

    • 300g 10⅝ oz Digestive biscuits
    • 75g 2¾ oz Butter (unsalted)
  2. Classic mode Step 2

    Press the mixture into a 20cm loose bottomed, greased flan tin and up the sides, pressing well with the back of a spoon.  Leave the base to chill in the fridge.

  3. Classic mode Step 3

    Using a zester, pare the rind from 1 lime into strips and set aside for the decoration. Grate the remaining lime zest and squeeze all the juice. Place the juice in a mixing bowl with the condensed milk and cream and whisk until thickened. Stir in the grated lime zest then spread the mixture into the biscuit base. Chill for at least 1 hour or overnight would be best, if time will allow.
