why do so many cookie recipes call for lemon juice and lemon zest?

ok so i have never been a fan of lemon in my pastries. so why do so many recipes call for lemon zest? im looking through a cookie cookbook and all the recipes call for lemon zest and/or lemon juice. but why? if i make it like the recipe says will it taste like lemon? or does the lemon act as some sort of balancing ingredient to balance out the sugar and butter or what not?

Any good cookie recipes that don’t use vanilla?

Hi, does anyone out there know a good cookie recipe that doesn’t use vanilla, because I don’t know for sure that I have any. Plus, I don’t have much else to do today. Thanks a lot!
OH, so it wouldn’t hurt not to use vanilla in a sugar cookie recipe? Well, I guess I can try that out. Thanks, and any other answers would be nice, thanks.
Oh, thanks for the call about sugar cookies without vanilla, I guess i’ll try to get some vanilla when I can, and not make the cookies today. Thanks!
