Orange Mamon Cake

I found this baking recipe from my mom recipe collection book. She kept this recipe for 10+ years and never try out. I decided to try out last weekend :)

Ingredients:
A) 4 egg yolks, 20 g sugar, 3 tbsp orange juice
B) 100g flour, 1/4 tsp baking powder (mix and sifted), 1/4 tsp salt, 1 orange zest.
C) 4 egg white, 1/2 tsp cream of tartar, 50g sugar
D) 50g melted butter

Directions:
1. Beat A till fluffy, add B and blead evenly.
2. Beat C till stiff and confine, add (1) and D
3. Scoop batter into paper cups until 3/4 full. Bake at 180°C for 20 minutes.

According to original recipe, baking powder should be 1/2 tsp, but I only figure out my baking powder on left 1/4 tsp when I prepare the ingredients, because of no time to buy new baking powder, I try to put only 1/4 tsp and luckily it work.

Regarding the sugar, original recipe was 40g for "A" ingredient and 60g for "D" ingredient, I cut of too much and my fresh orange juice was too sour cause the whole cake become "sour mamon cake".

Overall, this cake still consider delicious. ^^
