Cherry's?

I collect some of these most years but the tree is very well stocked up this year!
I normally just depip freeze and use in smoothies. So much on the tree I think I should do something else as well with them. Are they actually cherry's they are very yellow picture has them slightly green.

Are they cherries or Mirabelle plums?

I will go with Mirabella plums. There appears to be two types. One is slightly tart, this one is definitely not tart. Thanks I will just have find recipe for them. It appears jam is there main use.
