Hi Arline
thank you for your question.
Our recipes are developed in the 6 quarts and for most of them you will not need to divide the recipe in half (as long as the meat fits)
For recipes with a lot of liquid such as chili, soups, pasta, congees, stocks…etc, you will want to cut them by half in the 3qt.
The cooking time will stay the same!
Have fun cooking & please take care
Jacky
