How To Cook Creamy Onion Flan

Creamy onion flan

Pastry made with egg or milk as the binding agent gives the best result in the microwave. Covering the pastry with absorbent paper and a plate ensures that all the moisture is absorbed and the pastry stays crisp.

  • Pinch of salt
     

  • 50g (2 oz) sunflower margarine or white vegetable fat and butter mixed
