hi there! i have been making plain scones from *The Joy of Vegan Baking* and I would like to adapt the recipe to make orange poppy seed scones. I've been using the chocolate chip scone recipe, minus the chocolate chips, and the scones have been great. I'm just not sure how much orange zest and/or juice I should add to the mix. i am a disaster in the kitchen, so if it can go wrong, it will. does anyone have any tips?
