haven't had Apriums yet,but Pluots i've enjoyed the last few years.
For me the best way is simply eaten out of hand.There so intense and sweeter then plums or apricots on there own.
I know this is not how to spell this,but i've marinated them in slivavits and honey,roasted them and served them over Ben and Jerrys Vanilla ice cream
Instead of Roman apple cake i've done Roman Pluot cake.
I would say any way you like to prepare plums you can use Pluots,They have for of the plum color and flavor then the apricot.
