20ml milk (i used water)

Method:
1. Whip egg whites till foamy.
2. Add in sugar in batches and beat till soft peaks.
3. Add in yolks, one at a time, and mix well in each addition.
4. Add in extract and paste. Mix till combined.
5. Fold in flour.
6. Then fold in oil and mix well. After that, fold in milk.
