How to Make Sugar Free Lemon Curd

Spread on low carb bread for a sumptuous breakfast, ripple through Keto vanilla ice cream or use as a filling for pies and cakes! Sugar free lemon curd has many wonderful uses. If you're like me, you can even sneak a quick spoonful for a satisfying quick sweet treat.

Notes

1.6g net carbs per portion. Makes 12 portions.
Nutrition is based on 12 generous servings of 2 tablespoon each. This means you can enjoy 2 slices of bread with sugar free lemon curd for breakfast!
You can add the zest of 1 lemon to the recipe for additional zing.  Simply grate it into the mixture when you add the lemon juice. 
Allulose has 70% the sweetness of sugar, that's why you need to use more (pure) allulose than other sweeteners which have the same sweetness as sugar. I have given the recommended amounts for sweeteners in the ingredients.
