Lime curd is really easy to make, and it is so much better than ones sold in stores. You can use lime curd just like lemon curd, in cakes, pies, on toast or whatever you can think of...
2 limes (juice & zest)
1 dl sugar
50 g butter
1 tsp vanilla sugar
Wash the limes well and grate the zest. Split the limes and squeeze the juice. Add lime juice, lime zest, eggs and sugar to a saucepan. Stir over medium heat until mixture thickens.
Remove from heat and add vanilla sugar and butter in small pieces.
At this point the mixture slightly loosens, but it will thicken again when cooled.
Store lime curd in the refrigerator and use it within 2 weeks.
