You will also need a loose-based flan tin with a diameter of 9 inches (23 cm), 1 inch (2.5 cm) deep, and a solid baking sheet
Place the butter in a pan over the lowest heat and melt
Crush the digestive biscuits into a bowl
Add the melted butter and mix well
Place the butter-crumb mixture in the flan tin and, using your hands, press it down evenly all over the base and up the sides of the tin
Place it on the centre shelf of the oven for 10-12 minutes, or until crisp and golden brown.
While that's happening, combine egg yolks and lime zest in a bowl
Use an electric hand mixer & whisk for approx 2 minutes, or until the egg has thickened
Add the condensed milk and whisk for another 4 minutes
Add the lime juice and give it another quick whisk
Pour the whole mixture onto the baked crust and return it to the oven for another 20 minutes, or until it feels set when you lightly press the centre with your little finger
Remove it from the oven and let cool
Once completely cooled, cover with cling film and chill until needed
Serve cut in slices with crème fraîche and a twist of lime for decoration
