Add the freshly squeezed lemon juice, white sugar, lemon extract, salt, coconut cream, cornstarch and turmeric to a saucepan on medium heat and whisk together.
Keep whisking and alternately stirring until it thickens. Whisk even more vigorously when it thickens so that you make sure it's nice and smooth.
Remove from the heat and pour into a heat safe container and let it cool before placing into the fridge to store.
It will thicken more as it cools and even more in the fridge.
