Bigger is not always better.
We live in a society where bigger is usually perceived as being better and this philosophy even extends to our fresh produce. Unfortunately, many fruits and vegetables lose a lot of flavour and sweetness the bigger they grow.
When purchasing fresh produce the look, smell and texture of the fruit or vegetable is far more important than its size. This is important when purchasing strawberries, stone fruit, citrus, chilies and zucchini. But, the number one thing that is never better bigger is onions, especially the spanish (or red) variety.
