Citrus Curd Recipe

No-sugar-added Citrus Curd:

1 cup of citrus juice
the zest of one large citrus fruit
1 large egg
2 large yolks
1/4 cup of erythritol or xylitol
4 tablespoons of cubed butter
a pinch of salt

Whisk together the egg, yolks and sweetener until fully combined, then add the zest and juice until well mixed. Heat over low flame, stirring constantly, until it is thick enough to coat the back of a spoon and is just on the verge of boiling. If you have a thermometer do not let it pass 180F. Strain the mixture into a bowl and mix in the butter cubes and salt. Chill thoroughly before using.
