my mom adds a pat of bacon fat to just about everything she cooks that calls for fat/oil... this adds a layer of flavor to the dishes, and helps the food carmelize, giving it yummy depth... but i think it is also what has helped my mom and dad eat smaller meals throughout the years... he will be 91 soon, and she will be 89 next month... they are both healthy... fit...
