It’s usually the simple pleasures that delight me the most. I’m constantly amazed by the product of time and temperature. Slowly simmering fruit and a bit of spice can yield a jar of rich, silky fruit butter (like this Cardamom Pear Butter). Roasting broccoli and cauliflower takes both of those humble veggies to a whole different level. Puréed fruit and a low, slow heat produces chewy and sweet fruit leather.
