I'd never heard of this apple until a reader mentioned it, so when Ambrosia showed up at a local supermarket I had to try one. Place of origin was just listed as "Canada," and I'm guessing British Columbia, where Ambrosia was born.
This shapely apple has the tapered, wasp-waisted profile of a Red Delicious. There is an orange-pink blush in streaks over light yellow, with yellow-green lenticels (a bit darker than the skin) throughout. It is medium large and prominently ribbed, to the point of having distinct "chins" on the bottom. The calyx is tucked far behind those chins and is closed. Unbroken, the apple smells promisingly of cider and strawberries.
Ambrosia's crisp yellow flesh is medium-coarse-grained and very juicy. Its flavor is light and sweet with faint vanilla, melon, and banana notes. The slight hint of tartness, though enough to keep things interesting, does not really balance the sugar, but Ambrosia's lightness nonetheless skirts the pleasant side of cloying. My sample oxidized very slowly.
This is a refreshing sweet apple with some nice flavors, very good to eat this time of year. I'm getting some more of these.
Ambrosia is a chance-found pippin (ca. 1980) and although one blogger may be right when he claims it is a Starking Delicious - Golden Delicious cross, no one knows its pedigree absent DNA testing. (Update: More on this in the comments.) The BC Ministry of Agriculture and Lands has an Ambrosia fact sheet, and the discriminating reader may enjoy some cheerful Ambrosia propaganda (which includes a recipe for Ambrosia-accented cole slaw).
I was going to tag this a "winter" apple to distinguishing between local apples (even good keepers that I eat in the wintertime) and those trucked in from far away in the winter apple "season." On second thought, a system of classification based on when I eat an apple or how far it traveled to reach me is not really tenable or interesting to others. This Ambrosia was certainly harvested in the fall.
Note however that good keepers were once widely known as winter apples and this meaning persists today.
