Directions

Crust
Step 1
For the crust:
Note: This crust will remain soft even after being baked. If you prefer it less soft you can add the butter to the crumbs by hand rather than adding it to the food processor.
Step 2
Preheat the oven to 325 ° F / 170° C.

Place the cookies or biscuits or crumbs in a food processor. Add the nuts, the zest and the kaffir lime leaves. Whirl until mealy, add the melted butter and whirl again.


Step 3
Butter you cake tin, pie plate or dish 9’’, add the crumb crust and use you hands to carefully spread the crust over the bottom and make a small rim about 1/3 up the sides.

Bake in the oven for 10 minutes.– don’t worry if the rim shrinks a little. Remove and cool.
Cream cheese filling
Step 4
For the cheesecake filling layer:
Note: I prefer to mix this layer by hand to have more control. If you do use an electric mixer keep it on very low, do not overbeat the mixture.
Step 5
Turn up or preheat the oven to 350° F / 180° C – I used the convection setting so the moist air can circulate.

In a large mixing bowl beat the cream cheese and sugar until just smooth and then add the yoghurt, juice and zests, mixing to combine.
Now add the eggs one at a time, mixing just enough to combine after each one – don’t over beat or mix. Pour the filling carefully into the crust.
Step 6
Pour ca. 1 liter / 33 fl. oz into the dripping pan in the bottom of your oven.
Now place the cheesecake on a rack in the middle of the oven and bake for 45 minutes. Turn off the oven without opening the door and let the cake sit another 10 minutes. This helps the layer settle and not crack.

Remove the cheescake and cool.
Leave the remaining water in the dripping pan fort he next baking step.
Lactose-free sweetened condensed milk
Step 7
For the lactose-free sweetened condensed milk:
Note: If making your own lactose-free sweetened condensed milk this is your next step, if not you can skip this one and use canned sweetened condensed milk.
Step 8
Stir the cream and sugar in a small saucepan. Bring slowly to just boiling point, stirring in between. Lower heat and simmer for 4 minutes, stir frequently and then cool. Stir once more before using.
Top lime layer
Step 9
For the top lime layer:
In a bowl, beat the eggs and sweetened condensed milk until smooth. Add the lime juice, zest, salt and pepper if using and continue beating lightly until smooth.
Step 10
Using a large spoon, spoon the mixture carefully over the cooled cheescake taking care not to pierce the surface.
Smooth carefully and return to the 350° F / 180° C oven (with the water remaining in the dripping pan) and bake for a further 22 minutes.
Turn off the oven and let rest another maximum 10 minutes. This helps settle the layer.
Step 11
Remove and cool completely then refidgerate overnight.
