Tea: either is ok, get some sucralose (splenda) for her to sweeten it. I'm from the south so all tea is iced and sweet, 'cept sometimes in winter.
Caveat for the pie: I haven't actually made this but I have made similar pies for my folks (diabetes). Its simple to make.
Note there's no crust so you'll need a pie plateYou could buy a crust but I bet nobody makes a sugar free one. Everybody needs to have a pie plate anyway.
And a bit of advice: get enough ingredients to make two pies. Make one, like a practice run- if its ok then fine, if not or you want to go for better then freeze (or eat) the first one with your guy and make the second one now that you have practice.
Good Luck BtAegis!
