FB and CFB for freezing

My Dad used to do a pickled french beans that were yum - must pinch his recipe he hasn't done them for a while. I find it is how you freeze french beans rather than which ones. I use to blanch them, bag them, wrap with kitchen roll, then bag again - faffy but it made a difference and I told this to someone else and they had struggled but this worked for them.

Veggie do you eat beans anymore or are they still too squeaky???
