In a trip to central Washington, I bought a flat of Pluots (plum/apricot hybrids), and they were one of the most profound things I have ever eaten. So sweet and juicy, they almost burst like water balloons when you took a bite.
Less than four hours away from where they are grown, I have yet to find any varieties with the same magic available in grocery stores. They good ones are simply too delicate and too short lived.
It ends up being worth the trip every year to go when they are in season.
