hi Gravyyy (lots of y's!!!)
i think it is a really nice thing for you to do. and your old T i think will see it as (a) nice because you promised it and still remember and (b) a token of "closure" for you.
seriously if you wanted her to call you still, there are alot more annoying ways of trying to get her to call than sending a stuffed cabbage recipe....right? (i can think of a ton!

)
this is a very nice gesture and i think she will be happy.
PS: what is stuffed cabbage?
