Make your favorite tart crust. You can make the filling while the crust rests in the refrigerator. After filling the tart pan with the crust, put it in the refrigerator.
Peel the sweet potatoes and boil them. You could also cut them into small pieces, place them in a bowl with some water and microwave until tender.
[Filling:] Melt the butter and set it aside. In a separate bowl, combine the egg and sugar really well. Mash the sweet potatoes in a food processor.
[Note:] Make the sweet potato paste by adding milk into the sweet potatoes in 2 batches. Add a half portion of the paste into the filling at Step 3, then add the remaining paste and mix to an even consistency.
Add the margarine and other ingredients into the filling from Step 4. Add black sesame seeds or sweet potatoes with skin if desired.
Pour the filling into the tart pan. Sprinkle black sesame seeds on top. Bake at 170℃ for 40 minutes.
For the topping: Cut the sweet potatoes in 2-mm slices. Sauté the sweet potatoes in butter. Add honey and coat them evenly.
Once the filling from Step 4 is in the tart mold, arrange the sweet potatoes on top and sprinkle on the black sesame seeds. Bake at 170℃ for 40 minutes. Cool before slicing the tart.
I made a second version of a healthy tart recipe. I uploaded the recipe for the crust I make when I don't have tofu at home. It's a budget-friendly and healthy recipe. (Recipe ID: 989376)
Cheers to my fellow health-minded chefs!
For special occasions, like birthdays, decorate the tart with whipped cream and make it gorgeous. If you are health-conscious, replace the milk with soy milk. Check the sweetness of the sweet potatoes before baking!
Story Behind this Recipe
I simply wanted to make a sweet potato tart.
If you do not have a food processor, mash the sweet potatoes until smooth. Melt the butter at low heat. You can mix all the filling ingredients in a food processor, however, I think it comes out better when processed manually, even though it is a lot of work; that's why I revised the recipe to manually processing. As long as all the ingredients are mixed well, you will not fail!
