Pick the dandelions on a sunny morning so they are open and easier to pull the petals from. Hold the green leaves and pull off the yellow petals or snip them with scissors. The mild floral dandelion flavour goes well with the tart lemon in these vegan oaty cookies. I was juicing kale and added it to my sweet lemon drizzle to make these cookies even more special. You can't taste the kale, but it makes a beautiful green colour and the lemon drizzle is a bit less sharp than usual because the kale juice means less is needed for the right consistency. Cookies with leafy greens and sunny petals.
