I've looked up the usual places for meanings of nonpareil and have found unequalled and also its usage to mean small confectionary. However, I see it used on almonds, others have reported it being used on capers, and I'm guessing there's more to the gloss when it comes to nonpareil and food items.
Anyone know what it means—for instance—when on a package of almonds?
I would like to know the etymological differences between its "unequaled" meaning which seems to apply to confectionary and its meaning on other foodstuffs. Are all the usages just chefs trying to brag, so to speak, or is there more nuance as to how these variety names and/or size classifications (or other varieties of its usage) came about? I do think it's an interesting question about words and their etymologies and how one word developed its variegated meanings is of interest (in general) to English language aficionados.
