Mix the lime juice with the condensed milk.
Add the yolks one by one and mix immediately so the yolks don't oxidize with the sugar from the condensed milk or the acidity from the limes.
Pour onto the cookie base and bake in the oven still at 160°C/320°F for 20min.
Let cool down completely and place in the fridge overnight.
After this time, unmould the base and filling. To do this, run a knife around the edges without paper and lift it off using the paper.
