At this time the Recipe Analyzer is unable to recognize custom items - the ones you put in yourself. You can tag groups of items using the same tag and then add the entire group. when you tag them under one name, such as "pie recipe", and look over to the right side of your tagged screen, you'll see a little arrow next to the tag name. Click on the arrow and add the entire group.
I'm sorry I can't be more help. The Analyzer is a work in progress, but I don't see the programing problem of adding custom items to be solved any time soon. If you need help entering recipes, feel free to PM me.
The side effects of allergy medications keep some people from using them. Natural remedies can be a great alternative, but some are more effective than others.
