No one has mentioned this but the worst thing you can do when trying to teach them recall is punish them when you catch them or they come to you... Praise, treat, praise even if you have to make her come to you! If you're just going to yell at her or similar, why would she want to come to you? And don't let her off leash from now on until she learns to come when called.
