Can't figure out how to create a recipe- please help

I just signed up for Gold because I have given up on the Fitbit food app. I have so many custom recipes in that app and am trying to rebuild in chronometer but I can't figure out how to use that feature. I have the detail for fat, carbs, protein all entered down to the gram for each recipe so that I can measure my food and enter that way but Chronometer doesn't seem to allow me to enter the recipes that way. Does anyone have any tips?
