Ingredients

For the base

  • 250 g Digestive biscuits
  • 100 g Gingernut biscuits
  • 150 g Butter or baking spread melted

For the filling

  • 3 Egg yolks
  • 397 g Condensed milk
  • 4 Limes zest and juice

For decoration

  • 300 ml Double cream
  • 1 tbsp Icing sugar
  • 1 tsp Vanilla extract
  • Lime zest optional

Instructions

  • Pre-heat your oven to 160C Fan/180C/350F/Gas Mark 4
  • To make the base use a food processor to whizz up the digestive biscuits and ginger nuts into crumbs, or you can put them in a bowl and bash them with a rolling pin
  • Mix the melted butter into the biscuit crumbs and press them into a loose bottomed 23cm/9" tart tin
  • Bake the biscuit base for 10 minutes, take out and set aside to cool
  • To make the filling, whisk the egg yolks together with an electric mixer for a few minutes
  • Then whisk in the condensed milk
  • Add the juice and the zest of the limes and whisk the mixture for a few minutes
  • Pour the lime filling into the base and bake it for 15 minutes or until it is set, but it still wobbles a little. Let it cool completely
  • Whip up the cream with the icing sugar and vanilla, pipe or dollop it on top of the cooled pie then sprinkled over the lime zest
  • Serve immediately and store any leftovers in the fridge for 2-3 days

Notes

  • You can use either butter or a baking spread for the biscuit base.
  • I used a combination of digestive biscuits and ginger nut biscuits for the base, if you want to omit the ginger then you can use all digestive biscuits. Or if you want a stronger ginger hit, use all ginger nut biscuits. You could even add some ground ginger to the biscuit crumbs if you're a big ginger fan!
  • I piped the whipped cream on top of the tart using a Wilton 1M and Wilton 6B nozzle. You can also simply dollop it on top.
  • You must use condensed milk for this recipe, evaporated milk will not work.
  • A US cup measure or a shot glass make handy tools for pressing the biscuit base into the tin and up the sides evenly.
  • Although I provide cup measurements, I highly recommend weighing your ingredients out using digital kitchen scales*. It is the most accurate way to measure ingredients and will ensure the best results. Digital scales are very low cost and can be purchased for around £12 ($16.50) .
  • For teaspoon (tsp) and tablespoon (tbsp) measurements, please use measuring spoons* and not the type of spoons you eat with. Again this will ensure accuracy and provide the best results.
