Translation:My fruit is in the refrigerator.
Huh. I know "fruit" can definitely be singular or plural, but "my fruit are" sounds completely wrong to me and I can't explain why. (American, for reference.)
Friuts could be plural in the context of "the fruits of your labour" but fruit that goes in the fridge would take the singular verb i think even if there was a lot of it. You could say "pieces of fruit" and put them in the fridge
Fruit should never be plural in this type of sentence, no matter how many fruit you have. Fruit is always singular when referring to actual edible fruit
You have an apple and a banana. Those fruits are in the fridge. Using a singular here sounds really unnatural and strange to me. Perhaps it is really normal for a native English speaker. But for me it is really strange.
