Cable tinking

How do I fix a cable row with a mistake when every row has twisted cable stitches? My pattern has 1/1 cable stitches both RPC and LPC on each row forming tree branches. . If I pull the 2 cable stitches, it untwists the cable stitch on the row before it. Oh boy!!

What is the name of your pattern?
You might try pinching the sts as you pull out the working yarn or you could use a cable needle or spare needle to pick up the first stitch as the yarn strand pulls out.

The pattern is called Fir Tree Hat, found in ravelry.com.
Thanks for the tips!
