I would do bathtub taming and not try to handle her. Have a few toys in the bath - a tube and a hidey place. She'll probably run up the side of the bath slithering down again a lot. At the time, just try stroking her on the back with one finger ~(wearing your gloves if you feel nervous she'll bite). She may jerk round as if to bite. So wait and maybe 10 minutes later do the same thing again - a gentle stroke on the back with one finger. Then leave it till next session. I transferred our syrian to and from the bathtub in a hamster ball (lower it into the cage with a treat in and let her walk in then pop the lid on and carry her to the bathtub in it - sometimes I'd let ours have a little run in the ball first as an adjustment between cage and bathtub). Put the ball in the bathtub and take the lid off making sure it stays on its side with the entrance at the side, so she can hop back into it if she wants (wedging it against the plug helps keep it stable
Leave the ball there.
Maybe do bathtub taming every 2 or 3 days. Continuing with one little stroke on the back with one finger. Eventually she will stop jerking round as if to bite, and that is a big turning point - she is accepting touch. If she doesn't actually bite the first time you do it (but just jerk round and threaten to bite) then do it without gloves after that so she'll be getting used to your scent as well as your touch.
Once you can do that without her jerking round, move on to laying the palm of your hand upwards with your hand flat on the bathtub (palm up) just in front of her and let her walk over your hand (on the way to a toy eg). Next time you do that gently lift your hand 1cm or so as she walks on, but let her walk off again. Next time do the same but lift your hand a little bit higher, but still let her walk off.
After that, you should be able to hold her by making a tunnel with your hands and letting her walk between hands tunnel shaped (this also means she is feeling stroked all over while you're doing it). It can be slow but when it happens it can be instant.
It took two months of this with our last syrian who was terrified and ferral. But once we could pick him up the first time, he was tame as anything and very easy to handle after that. And be held and stroked. Bearing in mind they don't like sitting still too long.
So you'd be at the stage of being able to pick her up and hold her without her "pinging" (ie wriggling and leaping out of your hand about 2 feet in the air!).
I would leave food out of it and focus on her getting used to your touch and scent and building trust that your hand isn't going to hurt her.
