This lemon curd tastes just like a lemon pie and is delicious with crêpes (see recipe)!
In a pan, mix the sugar with the starch.
Melt the butter and add to milk, along with the lemon juice and zest and the turmeric.
Pour the liquid on the sugar mix, stir well, bring to the boil and simmer for about 10 minutes on medium heat, stirring until it thickens. Keep refrigerated for a week.
