My first step was to research soup recipe. It was important to have more of a depth, so I wanted to do them seasonally. Use two recipe for each season, by also using vegetable that grow in that season. So that the recipe also has more meaning nd more depth, from my interest in the theme and idea.
This is the page from sketchbook. It may look messy, but every recipe researched is put into the 4 seasons and highlighted the vegetables. Which I have narrowed down to what I think will work best, thinking about the colour of the vegetable. Colours that will possibly work well together.
