Lemon Yoghurt Muffin

It was May Day and husband had a free day! Yay! You know that it's nice to have a warm muffin for afternoon tea so i decided to make this one.
Here is the recipe for 2 ramekin cups.

6 tbsp all purpose flour
5 tbsp plain yoghurt
1 egg
1 tbsp vegetable oil
A pinch of salt
3 tbsp orange juice
2 tbsp lemon juice
1/2 tbsp lemon zest
30gr sugar
1/2 tsp baking powder
1/2 tsp baking soda

Preheat oven at 170 degree celcius.
Whisk egg and oil together. Add yoghurt to the mixture. Mix flour, salt, baking powder, and baking soda then sift into the previous liquid batter. Stir evenly. Dilute sugar in orange juice then add lemon juice and lemon zest to the mixture. Combine the juice with the batter. Prepare ramekin cups, apply butter to inside ramekin's side. Bake in two cups ramekin for 25 minute.

Ps. My oven heat was not even, it made my batter bleed :(

Smakelijk!
