What’s a good substitute for lemon juice??

I’m making and apple pie for thanksgiving and I haven’t made one in years so of course I forgot Lemon juice and there’s no way I can go back to the store so I need a good substitute 🙌

Update: sorry I didn’t get back to y’all last night , I decided to go with recipe that didn’t use lemon juice but I sprinkled the apples with a little apple cider vinegar about half the amount you would use with lemon juice just for some tartness and to keep the apples from browning

I’ll let y’all know how it turns out and post a picture 🙌💕 Happy thanksgiving 🦃🍁
