When praying for a person it is important to mention the person’s Hebrew name and that of his/her mother (for example Yaakov ben Rivka). If the mother’s name is not known it is possible to substitute Sarah (Yaakov ben Sarah) because all Jews are the descendants of this matriarch.

Also, you should include the person in the general context of other people needing the same thing (“among other sick people of Israel” is the accepted wording). This way the prayer does not single out just one person when it can benefit many others.

Something along the lines of “Hashem, please send speedy recovery to (person’s Hebrew name) son/daughter of (mother’s Hebrew name) among the other sick people (or whatever the problem) of Israel” is an accepted form.

Thanks for reading. It’s not too hard, especially if you have a good food processor/mixer that does the kneading for you. There is a recipe for challa in my recipe section, and there are lots of other recipes online. I’ll try to put together a post on some challa-baking basics.
