Why isn't life a bowlful of cherrieses?

What a treat it is to see Ontario cherries come into season. “Cherry” comes from a Latin word, ceresea, which became the French word cerise (in Northern French dialect cherise). Why is there an s on the end in French but not in English? In fact, there used to be an s in English as well. You would have one cherise and many cherises (because who can stop at just one?). But this was too much for English-speakers, for whom an s ending suggested a plural, so they dropped the s in the singular and made it “cherry”.
