I made a coconut cream pie not long ago, I think the recipe was by Cook’s Illustrated. It had coconut milk and coconut in it.
Weirdly enough, it didn’t taste much like coconut at all.
If I were doing it again (and I may well someday, I love pie), I’d take a look at Alton Brown’s Coconut Cake recipe.
He used coconut in varying ways throughout the cake, Coconut milk, coconut cream, coconut extract, coconut itself ... .
You might want to take a look at his recipe.
I adore the taste of toasted coconut, I can’t help thinking that would taste really good with peaches.
