Natural selection
The sweet fruits got eaten, and the seeds spread, causing those plants to thrive, and reproduce, and so on
the ones that were bitter didn't get eaten, and therefore couldn't spread and thrive and eventually died out.

It's the same, they just ended up adapting differently.
The basic premise still applies, one plant mutated to be sweet/sour/bitter/spicy etc It's neighbour plant mutated to be less so
Animals/humans liked one version more, and liked the other version less, so those plants get eaten, and the seeds get spread
In some cases, humans specifically liked certain tastes so we manually selected and bred plants with specific mutations and variations to get the flavours we wanted
