I see it as this: being a Venn diagram, it is showing relations between all outer ring ingredients. so where it overlaps it shows the relationships. i.e. top left (butter) + bottom left (sugar) are components of middle left (whipped cream) so these items are related. same with groupings of 4, i.e. top left (butter), top middle (cooked egg), middle (cake), and middle left (whipped cream) are all linked as they all contain butter. the same continues for each side, and each grouping of four within a circle, and then the middle (cake) is linked to everything since they all the outer items have a least one ingredient in common with cake.
