First, zest the 2 lemons and juice both of them in a bowl, add the zest to the lemon juice
Combine the cream and sugar in a pot and bring to a simmer. Make sure to stir the whole time or it may burn
When it starts simmering and bubbling, the cream will start to have a yellowish hue. Let it “bubble” for 2 minutes and transfer it into a mixing bowl. Let cool for 2 minutes
if you make this dessert and it doesn’t thicken much(you can still eat it) , let it boil an extra 30-60 seconds next time.
Add the lemon juice into the cream mixture making sure to stir it well else the acidity will make it curd.
Pour into your glasses, ramekins or whatever container you want to use to serve this. Transfer to refrigerator for at least 4 hours
These will be good the next day, I recommend covering them with plastic film after a few hours to prevent your custard from capturing fridge odour.
