Congrats! Glad everything turned out well - maybe you could post your recipe for us?
Don't mean to sound preachy, but if you're going to be making food for resale, you should definitely take a food safety course (usually through the local tech college or adult education folks); or at least do a seach online to find out more information.
If you're cooking out of your home and someone buys something that's not good, your brother, his business and you could all be sued.
Most of the information is common sense anyway, but if you had taken this course, you would have learned about cooling large batches of food to prevent spoilage.
