I always recommend a sensible diet, including lots of carbohydrates and avoiding too much fat. Dancers don't need different fuel from other people - they just need more of it because they use more energy. ↗
I always have a good quality extra virgin olive oil. A cheap quality oil will end up cheapening your dishes. And I love sweetening my dishes with maple syrup. It has a bit of a bitter kick at the end that works wonderfully in savory dishes. ↗
I know, speaking for myself, no matter what I'm able to do, no matter what book comes out and ends up on paper, I always had something bigger and grander in my head. ↗
