Three foods where it is important to have the optimal ratios:
1. Butterfinger. The little mini ones (most prevalent at Halloween) are the perfect ratio of chocolate covering to inner candy. The tiny Butterfinger balls have too much chocolate, and a regular size candy bar (or certainly the giant size) has too much inner candy.
2.
Onion Rings. Can be rendered noxious by having too much onion.
3. Hotdogs. "Jumbo" hotdogs have too much inner in proportion to surface area.
