why does my tzatziki sauce taste so bitter?

i decided to try my hand at cucumber salad, with a tzatziki bc i’m obsessed with it. funnily enough, i hate greek yogurt. the smell makes me gag and i find the taste to be too bitter (yes even the sweetened greek yogurts out there). but i’m obsessed with tzatziki because it literally tastes heavenly. I added: 1 cup greek yogurt 1 lemons worth of juice 2 cloves of grated garlic added a decent amount of dill (didn’t measure but i love dill) as well as salt and pepper i’m pretty confused because the smell of the yogurt is still super strong and even with the other flavors it’s really all i can taste. did i mess it up somehow?? please help!! i don’t know how restaurant or store bought tastes so different submitted by /u/anonymousposting5693
