I'm making a lemon yogurt cake, which called for 1 1/3 c. sugar, divided. I was supposed to save 1/3 to go along with 1/3 lemon juice to pour onto the cooked cake. I went ahead and added the whole amount to the batter. Now I am wondering how much sugar should I add to the lemon juice to pour over the cake, I don't want it to be too sweet since the cake itself will already have too much sugar.
TIA!
