Why are strawberry seeds on the outside?
Strawberries are unusual among edible fruit in having their pips exposed on the outside, rather than nestled within the flesh. The fleshy, edible parts of most fruits are formed from the ovaries – the parts that contain the seeds – which swell after pollination. A strawberry, though, is formed from an enlarged receptacle, the part of a flower on which the ovaries sit. So, what look like seeds are, in fact, tiny individual ovaries, each housing a seed within. This means that, in botanical terms, a strawberry is not a true berry, though most people are happy to overlook this technicality when making a summer pudding.
