Gluten free, dairy free, because it's supposed to be.
This cake is a riff on an almond, olive oil and lemon cake. Almond and egg foam cakes, while perfect for tea can be quite dry. Almond and olive oil cakes can be delicious, but I almost feel like the addition of some all purpose flour kills the purity of using what is around for this cake. Potatoes, while they might seems dense and heavy once cooked, tend to add a lightness and moisture to whatever bread recipe they inhabit.
When I hang out with my Canadian family, there are always potatoes around. My Uncle Robbie does justice to the humble potato every time. Boiled, roasted or grilled and tossed with herbs and oil or a knock of butter. In the case of this cake a leftover simple boiled potato was used, peeled please.
Anyone can make this cake. Stack it with fresh fruit and have a tremendous, allergy free (nuts yes please) cake, made without substitution.
2 cups Almond Flour (finely ground and firmly packed)
1/2 cup Boiled Potato (firmly packed and then afterwards riced or mashed with a fork)
1 Tbsp Cornstarch
1/2 cup Granulated Sugar
Zest of One Large Lemon
1/4 tsp Salt
1/2 tsp Baking Soda
1 tsp Baking Powder
3 ounces freshly squeezed Lemon Juice
4 ounces Olive Oil (mild olive oil works best. Save the spicy stuff for dressing your salad)
4 ounces lemon juice
2 ounces water
6 ounces granulated sugar
zest of one lemon

10. Place second layer on top and top with additional fruit and almonds.
