In a saucepan whisk together Orange (1), Granulated Erythritol (50 gram), and zest of a Egg (4) and Lemon (1).
Sift in the Corn Starch (30 gram) and whisk until combined.
Next squeeze in the juice of an orange and slowly pour in the Oat Milk (400 milliliter), whisking constantly.
Bring mixture to a gentle boil over low heat, stirring constantly with a wooden spoon. You can use this cream with cakes or serve it as it is with a side of fresh fruit.
