Is there a scientific proportion of sugar to yolks/citrus juice when making curd? For example, I'm trying to come up with a curd recipe that has as little sugar as possible because it will be sandwiched between 2 rather sweet cookies. Will it affect the stability if I halve the sugar in the following recipe?
125 ml tangerine juice + zest
62ml lemon juice
1/4lb butter
4 oz sugar
8 yolks
Thank you.
