This is my collection of my most used simple recipes that can help you go zero waste. They are often staples which are also used to make other foods or they are an easy way to use up leftovers.
When baking and cooking I often sequence things so I can reuse pans without needing to wash them -- for instance, I'll make dog treats first on baking sheets, then granola, and finally chocolate chip cookies because the dog treats leave the pans pretty clean, granola just leaves a little on the pans, but chocolate chip cookies leave a bigger mess on the pans and chocolate is not good for dogs.
Note that I make my own brown sugar and sugar syrup -- two basic staples in a lot of cooking. Purchased brown sugar usually comes in a plastic bag and most syrups in plastic bottles whereas granulated sugar comes in paper and molasses in glass (with a plastic cap). The syrup I make is stored in glass jars in my fridge since it has no preservatives.
