> 14-15 alphonso or ataulfo mangoes

Alphonso and ataulfo are not the same thing, not even close except they are both mangoes.

Alphonso is a uniquely fragrant and flavorful variety from India which is very rare to find in the US but you should be able to find it canned in pulp form.

Ataulfo is an ordinary mango from Mexico that is available everywhere in CA, including in organic form at Costco.
