Since you can’t really taste or smell, your best bet will be to follow recipes and hope for the best. Approach cooking like a science. Measure at all points during the process. Measure out all the ingredients and prepare then ahead of cooking them. When cooking meats, use a thermometer to measure the temperature of the meat to make sure they are cooked.
Its always better to undersalt things than over salt. You can always add more salt but can’t remove it. You can pre salt things and hour before and this will help even out the saltiness of most things.
I record events of the day, daily. Going on a year now. Just a quick jot of the most eventful thing of the day. Nice to look back and remember things that happened through out the year.
Use an app called “Daily You” in F-droid to help me organize it all, if anyone is interested.
