We have a few GF folks coming to Thanksgiving (including kids), and I've offered to do some baking especially for them. I have never done the GF flour + xantham gum recipes, so I'm just trying to find tried and true (and delicious!) recipes that happen to be GF. I've enjoyed making Elizabeth David's flourless chocolate cake in the past, so I thought I'd do that. I'd like to try to pre-cut the flourless choc cake into petit-fours, so there's more to go around and the portions are automatically small (it's so rich, and lots of other folks will be having pie too). I'm worried about it being too sticky to do a clean job of cutting. Thoughts on how to make this look nice/festive? Thanks!
