My husband stays home more in his retirement and has learned to bake bread.  It has become his hobby-obsession.  And to procure all the exotic ingredients, he takes long walks in our town and gets exercise.  He loves kneading it and eating it.  He suggested contributing it to homeless shelters but I said that was going too far.

 Also I help and have learned to make yogurt.  I bought a little machine after many frustrating attempts. (You can make it with a thermos.)   It is very good yogurt, esp for smoothies with fruit.

 Also I buy good cookbooks in second hand stores and we are both learning to cook much much better and avoid restaurants.

 
Apologies if these are repeats.
