Orange Sponge Cupcakes

Tips for making orange sponge cupcakes:

1) Mix the flour with the eggs first, before adding orange zest to the batter. It protects the eggs from the acid in the orange peel. If you add the zest before or with the flour, the batter will become thin and bubbly. The bubbles won’t magically disappear in the oven, so your cakes will be full of big holes.

2) Use processed orange juice. Fresh OJ isn’t heat stable. Its flavour deteriorates when heated. 

3) After adding orange zest and juice, along with oil, the batter must be folded with a spatula, quickly and gently. A whisk would result in overmixing, allowing the acid to attack the eggs. If the batter becomes bubbly and runny, you can wave goodbye to your cakes.

4) The oven must be at 190°C. If the temperature is too low, the cakes set too slowly, giving the orange zest and juice time to attack the eggs.

Fresh OJ’s flavour deteriorates when heated. This recipe uses processed orange juice, which is heat-stable. Work quickly when you’re making the batter. Don’t let it deflate before it’s baked.
