Cleanliness is very important. If you let kids make a total mess in the kitchen and then leave, you're not really teaching them anything.
I make some of my best recipes with a simple homemade stock. Keep shrimp shells stored in a plastic bag in the freezer. When you have almost a gallon-bag full, you can make a stock in 30 minutes that you can use in soups and sauces. You can then freeze the stock in ice-cube trays.
You gotta have good olive oil. You should have a cooking olive oil and you should have a finishing olive oil, like an extra-virgin olive oil.
If you don't follow your dream, who will?
I can't tell you enough about cinnamon. Cinnamon is an awesome spice to use and it goes great with something like apples in the morning or in a mixture of fruit or in your oatmeal or even in your cereal.
