Depending on ripeness, thinly slice or mash persimmons, making sure you remove any seeds. Blend in a blender until pureed.
Pour the persimmon puree into a sauce pan on warm while preparing the rest of the batter to bring out the aroma & flavor of the fruit. Warming the persimmons also keeps fats melted when added into the batter.
Preheat your oven to 350°F (175°C). Grease and line a loaf pan with parchment paper.
In a large bowl, combine the almond flour, gluten-free flour, tapioca flour, flax meal, baking powder, cinnamon, nutmeg, cloves and salt. Mix well with a whisk or fork.
Separate the egg yolks from the egg whites, setting the three egg whites aside in a small bowl and putting two egg yolks into the second large mixing bowl, designated for wet ingredients. Discard the third yolk.
In a second small mixing bowl, mix the honey and butter with an electric hand mixer until smooth and creamy.
Add the pureed persimmons, vanilla extract and creamy honey/butter mixture to the egg yolks and gently mix together with a whisk.
Fold the wet ingredients into the dry ingredients with a spatula and mix until well combined.
With clean hand mixers, beat the egg whites in the small bowl until they begin to form peaks, then set aside.
Just before baking, fold the foamy egg whites into the batter and gently, but fully combine all ingredients with a spatula or with a hand mixer on low. If using a hand mixer, you will only briefly mix the batter. DO NOT over mix.
