I was interested in what some of these were and look them up, for at least the Jicama and the Ugni, they look nothing like the pictures you used (unless there is some regional difference in naming). The jicama looks like a root vegetable not a pea pod.
You need to take into account regional differences in names. Swede is called rutabaga in North America.
Would also be nice if you accepted broader answers:
- Plurals/singulars as acceptable answers (wouldn't take pea for peas)
- Simplified answers (honeydew for honeydew melon)
- Common misspellings (kolrabi for kohlrabi, etc)
Really enjoyed the quiz even if it did make me hungry!
