Preparation
- Heat the oven to 160C/fan 140C/gas 3. Whizz the biscuits to crumbs in a food processor (or bash in a plastic bag with a rolling pin), mix with the melted butter, and press into the base and up the sides of a 22cm loose-based tart tin. Bake for 10 minutes, then remove and cool.
- Put the egg yolks in a large bowl and whisk for a minute with electric beaters. Add the condensed milk and whisk for 3 minutes, then add the lime zest and juice and whisk again for 3 minutes. Pour into the cooled base and bake for 15 minutes. Cool, then chill for at least 3 hours or overnight.
- To serve, remove the pie from the tin onto a plate. Softly whip the cream and icing sugar together, dollop or pipe over the top, and finish with extra lime zest.
